Effect of Contact Pressure and Frequency on Contact Heat Transfer Between Exhaust Valve and its Seat
The hot gases produced by the internal combustion engines passes through the exhaust valve and causes high temperatures in the exhaust valve and its seat. To avoid damaging the exhaust valve, heat must be transferred from the valve to its seat during the contact they make at the opening and closing cycle. Heat transfer rate from the exhaust valve to its seat is a function of many factors. One o...
متن کاملSensitivity Analysis of Different Parameters Affecting Thermal Contact Conductance
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 ...
متن کاملReducing Hardware Complexity of Wallace Multiplier Using High Order Compressors Based on CNTFET
Multiplier is one of the important components in many systems such as digital filters, digital processors and data encryption. Improving the speed and area of multipliers have impact on the performance of larger arithmetic circuits that are part of them. Wallace algorithm is one of the most famous architectures that uses a tree of half adders and full adders to increase the speed and red...
متن کاملInvestigation on Ring Valve Motion and Impact Stress in Reciprocating Compressors
This paper presented the theoretical and experimental investigation on ring valve motion and impact stress in a reciprocating compressor for a purpose of extending the life time of valve. A simulation model was established to describe the motion of valve plate and the physical behavior of valve plates during compressor operation was measured using an eddy current displacement sensor to validate...
متن کاملEffects of Impeller Gap on Rotor Vibration in a High Speed Centrifugal Compressor: A Numerical and Experimental Analysis (TECHNICAL NOTE)
Centrifugal compressors produce high pressure ratio and rotate at speeds. So, a tiny unbalance can produce severe vibration. In this paper, effects of impeller gap on rotor vibration in a high speed centrifugal compressor is investigated. For this purpose, a numerical and experimental analysis are carried out. The moving reference frame method in FLUENT software is used for modeling of geometri...
