In this work, influences of the variety of parameters on the heat transfer forced convection of two confined impinging jets such as inlet geometry and mass flow rate have been investigated numerically. Simulations were done by using 3D k-ε model for incompressible flow on two jet exit geometries comprising rectangular and circular jets at dimensionless jet to plate distance of 2. Equations were discretized by a finite volume method. Local Nusselt number was obtained for various mass flow rate and geometries for air and pure gases of oxygen, nitrogen, Argon and carbon dioxide at dimensionless jet to plate distance of 2. As the mass flow rate increases, heat transfer enhancement was obtained. The CO2 gas has the highest level of the Nusselt number in comparison with others and around 40 percent increases the rate of heat transfer compare to the air thus it could be very useful in cooling process rather than other gases. Also this study revealed that the forced convection heat transfer in the circular jet has the higher amount than the rectangular jet.

In order to analyze the interactions among various components of hybrid contra-rotating shaft pod (HCRSP) propulsor and effects of test devices, the model test of HCRSP propulsor was conducted in a cavitation tunnel. In the present study, the interactions among fore propeller, aft propeller and the pod of HCRSP propulsor are analyzed with the influence of long-axis dynamometer. It is found that long-axis dynamometer shows great influence on pod propulsor which is made up of a pod and an aft propeller, but little influence on the fore propeller. Especially, under the condition of using long-axis dynamometer or not, the difference of thrust coefficient and torque coefficient of aft propeller with high advance coefficient reached 10%. Besides, fore propeller could accelerate the flow of pod propulsor. In detail, the pod and aft propeller show blocking and suction effect respectively, and these impacts could cancel out each other within a certain range.
