The ventilation system plays a crucial role in every building. Proper design and optimization of its operation increase the comfort users due to efficient air exchange at same time control velocity rooms. aim this paper is analysis effect plenum box entry on profile concerning diffuser face panel. This issue may sometimes be ignored stage but can significantly affect airflow from consequently r...

Aiming to solve the problems of low electrolyte flow rate at leading edge and trailing poor uniformity end clearance field during electrochemical machining (ECM) diffuser blades, a gap simulation model was established by designing three liquid-increasing channels cathode. The results indicate that hole channel (LIHC) with an outlet area S 1.5 mm2 distance L from center point 3.2 mm achieves opt...

Numerical simulations of the large constrained deformation of polymeric structures frequently involves, at some stage, geometrical situations which are diicult to model. These are in addition to any diiculties encountered in the description and in the implementation of complicated con-stitutive relations. In the case of thermoforming the dii-cult geometrical situations occur as thin polymeric s...

Nowadays, tube bonding in vehicles structure is noticeably considered by many researches. In this paper, local tube compression process by a rubber ring has been studied. Firstly, simulation of the process was performed by FEM. Then, experimental test has been carried out to validate the numerical results. Numerical and experimental results were compared showing a good agreement. In the second ...
