Numerical investigation of the effect of inlet skew angle on the performance of mechanical vapor compressor

► We analyzed the effect of inlet skew angle to the performance of compressor. ► Increasing inlet skew will increase the pressure ratio and efficiency of compressor. ► Higher inlet skew angle flow pattern clearly seemed less of secondary flow. ► Less of secondary flow, the system will be more stable and lower losses in operation. ► Lower losses in operation will increase the efficiency of MED-MVC system.
