This paper describes experimental efforts towards obtaining relative permeability for two phase flow in a homogeneous porous medium under adiabatic unsteady-state conditions. The porous media used in the experiments were Berea sandstone core samples. Porosity and permeability were measured using a routine core analysis while relative permeability is measured by core-flooding and mercury injection in special core analysis. Accurate relative permeability data is an essential input parameter for many reservoir engineering applications. Methods of [Kr] determination are discussed with specific emphasis being given to the calculation of the relative permeability curves from unsteady state displacement experiments. This study showed that relative permeability could be calculated satisfactorily by choosing a suitable model, especially in drainage processes. In the reverse procedure, capillary pressure could also be computed once relative permeability data are available.

This paper discusses the effect of using waste-cooking-oil-biodiesel with/without the use of Magnetic Fuel Conditioner (MFC) on the performance and emission characteristics of a 4-stroke, direct injection, water-cooled compression ignition engine at full load. Waste cooking oil obtained from the Faculty of Engineering and Technology cafeteria at the University of Jordan was converted to biodiesel through the process of transesterification. The product was first tested for its required properties and compared with those for petrodiesel. Then the engine was run with pure diesel and biodiesel to set the reference performance. After that, the MFC was installed and the same experiment was repeated on both fuels. The engine speed was varied between 1000 to 2500 rpm. Higher values were not possible due to excessive engine vibration and leakage in the exhaust. It was found that brake torque, brake power, brake mean effective pressure and the thermal efficiency of diesel fuel performed better than biodiesel, while with the effect of MFC, both fuels performed much better. Whereas, the brake specific fuel consumption for diesel fuel was lower than biodiesel, while with the effect of magnet, both fuels showed improvement in the reduction of MFC. Furthermore, it was concluded that there was a favorable effect of using MFC on engine exhaust emissions.

As part of the ongoing NGC-project (Next Generation Car) related to the research of new technologies for future road vehicles at the DLR, this publication is dedicated to the replacement of slip rings by an inductive power transfer system for field winding supplies in electrically excited synchronous generators. By means of function integrated lightweight design, due to the attachment of the rotary transformer as well as the co-rotating rectifier on an existing fan and the usage of standardised components for the rotational transformer, a volumetric optimized mounting as well as cost-effective brushless transfer system can be realized. The design of the system regarding the integration into the constraint space includes a variety of different challenges, which are subject of this work. For design purpose, an analytical model of the inductive link, the compensation network as well as the primary and secondary side power electronics has been set up. Furthermore, a prototype system has been established, measured on the test bench at the institute of vehicle concepts and compared to the derived model.

This paper (Part II), together with a companion one (Part I), deals with the fault-tolerant operation of a 5-phase permanent magnet (PM) brushless DC (BLDC) drive. In particular, this paper takes advantage of the drive model formulated in Part I to determine automatically the motor current supply, namely scheduling and magnitude of the currents for the surviving phases, in the cases of a drive with two and three open phase faults. Maximum magnitude of the supply currents is also determined by equating the rms value of current in the most solicited phase to the nominal rms value Open faults of adjacent and non-adjacent phases are studied and for each fault location, besides determining the motor current supply, the torque developed by the motor is calculated. The results indicate that the reduction in the motor torque as well as the extent of the torque ripple is depending on the relative location of the faults.

Plug-in Electrical Vehicles (PEVs) are nowadays increasingly penetrating the car market. Charging stations are becoming a lucrative business especially for the public parking lot owners where they can be installed and operated. PEVs can be used as energy storage elements during low demand and as energy sources during peak demand. Some technical problems related to the management of the charging stations may arise. Simultaneously charging a large number of PEVs in a parking lot may disturb the power system due to an unexpected peak demand. To overcome this situation, some researchers are suggesting different forms of Charging and Discharging Schedules (CDS). A reliable model for the flow of vehicles entering/leaving the parking is very essential to define an accurate CDS. In this paper, a new approach for modeling the flow of vehicles is developed, and it is shown how a CDS is related to it. In addition, it shows how incentive programs can contribute to increasing the financial benefits and at the same time reducing the disturbances on the power network.

This work proposes an algorithm for the elimination of switching ripples caused by the commutation of power semiconductors used in STATCOM. LCL-filter is a favorite solution to achieve this goal; however it reduces the stability of the system with the presence of resonance phenomena. Passive damping resistor can be inserted in series with capacity of LCL-filter to solve this problem. The LCL-filter is divided into three parts in order to reduce the interaction between filter components and the complexity of the control algorithm. Moreover, in order to improve the dynamic of the system, a cascade PI control is proposed. Different design steps are presented with damping resonance phenomena using a resistor connected in series with the capacitance. Our investigations show that the Total Harmonic Distortion (THD) of voltage and current injected into the grid tends to zero. That means, the passive damping LCL-filter attenuates the major part of current ripples compared with results obtained by using L-filter.

The paper deals with an approach to diagnose and remediate the faults affecting the Hall Effect sensors equipping brushless DC (BLDC) motors. The proposed approach is basically made up of an algorithm capable to detect, identify and remediate the fault in any of the three BLDC motor Hall Effect sensors. Following the detection of the fault, pointed out by a sensors binary word “000” or “111”, the algorithm allows the identification of the faulty sensor. A dedicated procedure is implemented for the sake of reconfiguration of the Hall Effect sensors-based control strategy. Simulation works, carried out under different faulty scenarios, have proven the performances of the proposed approach.

This article is concerned with controlling a servomechanical force system applied in the joining of thin-walled metal elements when manufacturing e.g. car bodies. The new, i.e. servomechanical electrode force control system is both an element and a parameter of a technology used for joining metal elements by means of resistance welding. The projection welding of 1.5 mm thick DX53 sheets was used to exemplify differences between the two i.e. pneumatic (classical) and servomechanical welding machine electrode force systems. An innovative solution applied in the servomechanical force system consists in using a hybrid algorithm in order to control the force and travel of welding machine electrodes during welding. The article presents the optimisation of the new, i.e. servomechanical electrode travel system being an alternative to the classical, i.e. pneumatic electrode force control system. As a result of the undertaken optimisation it was possible to increase the repeatability of a welding process and improve the quality of joints.
