Uncertainty analysis on performance of double stage reciprocating air compressor with inter cooler

Abstract

Air compressors are originating an extensive variety of situations for many processing industries, manufacturing industries and power sector. According to the energy conservation and management point of view the compressor is the main device which attracts the observation of energy engineers in many industries. For analysing the performance of the air compressor it is mandatory to measure the working parameters such as pressure, temperature, mass flow rate of air, motor speed and power. Since the measurement and instrumentation is playing a vital influence on the performance of air compressor. Therefore investigating the error on instrumentation and its influence on performance of air compressor is compulsory to regulate the eminence of experimental set-up. And these error factors will designate the effect of the uncertainty cause on the performance of air compressor. In this research work, a numerical study on uncertainty analysis were done in a double stage reciprocating air compressor with inter cooler setup which is located in sathyamangalam, Tamilnadu, India. The mandatory output for numerous applications were considered and taken for this numerical analysis of double stage reciprocating air compressor with inter cooler as per the local ambient conditions. The pressure ratio is varied from 3 to 7 in the selected experimental setup for the fixed mass flow rate in a double stage reciprocating air compressor with inter cooler. For the corresponding pressure ratios the uncertainty on the performance of air compressor based on the first law and second law analysis were mathematically modelled. Based on the model the uncertainty on the performance of compressor were found for the error of 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 1%, 2% in all the instruments and it was discussed in the result.
