Several studies have been made on unstable MHD Casson fluid flow past a perpendicular channel due to its significant executions in science and technology. For that reason, the major objective of the present article is to derive exact solutions for unstable free convection MHD flow of Casson fluid through a vertical channel. Employing suitable dimensionless variables, dimensional regulatory equations are transmuted into dimensionless form. Method of Laplace transform (MOLT) is applied to get analytical expressions for velocity and temperature of the flow. The acquired analytical results were plotted against different critical parameters to understand the flow phenomena. The obtained results are compared with earlier work with some limitations. The outcomes are in well concurrence with the existing ones.

In order to improve conveying and crusher throughput performance, major open pit mines are increasingly using high energy blasting. Strict and effective controlled blasting methods are required to protect the integrity of the pit walls from the increasing energy concentration. The M’haoudatt mine lacks pre-split procedures, which has led to unstable slopes and landslides that have increased the strip ratio. In order to correct mining anomalies, this work intends to evaluate pre-split practice. The aim of the work is to evaluate the pre-split performance in the M’haoudatt mine through tests carried out on one of the pit benches.

Spraying water upstream of an air-cooled condenser allows to reduce the temperature of the inlet air flow and to obtain additional heat transfer gains when the water droplets impinge on the condenser outer walls. It is therefore a very effective method for improving the energetic performance of refrigeration systems. In this work, a prediction model of the wetted outer surface, well suited to finned-tubes air-cooled condensers and based on purely geometric arguments, is investigated. The wetted outer surface is expressed, in case of a spray normal to the impact area, as a function of the nozzle-condenser parameters. It is found that the condenser wetted outer surface increases with the spray angle, the spray-wall distance and the collected water flow rate. On the other hand, when the latter reaches a value of 0.009kg.s-1, the wetted area no longer increases with the collected water flow and becomes a constant at 0.07m2. It is also found that the condenser wetted outer surface is always greater with finned-tubes than with smooth tubes.

Possible approaches to modeling heat and mass transfer in complex and little-studied physical processes are considered. The prognostic possibilities of empirical and theoretical models are discussed. A procedure for matching elementary transport phenomena with each other, realizing various mechanisms for given geometric, physicochemical and regime parameters is proposed.
