BACKGROUND: Cavitation is a phenomenon that occurs in vane hydraulic machines: pumps, turbines, when the pressure certain area of flow reaches level saturated steam pressure. Its occurrence depends on design and mode operation turbine. In order to turbine with high cavitation qualities, it necessary be able reliably predict this phenomenon.
 AIMS: The article describes approaches modeling ...

In internal combustion engines, exhaust valve and its seat gain considerable temperature as the hot gases exit through them. So, the rate of heat transfer should be under control. In this study, the contact heat transfer coefficient has been estimated. An experimental study on an Air-Cooled internal combustion engine cylinder head has been considered. Using the measured temperatures of sensors ...
