    abstract = {Valve design is one of the most important aspects of compressor 
  design. In designing the valve system for reciprocating compressors four main 
  features related to the valve performance are sought: Fast response, high mass 
  flow rate, low pressure drop when opened and good backflow blockage when closed. 
  For this reason and in order to obtain an optimum valve system, it is crucial 
  to recognize and predict the phenomena associated with the flow through the 
  valve. The present research is to analyze the effective flow area across the 
  valve section of a hermetic compressor with back flow condition experimentally. 
  Mass flow rate has been an important parameter in analyzing the effective flow 
  area at the valve section. Experimental set up being arranged in order to compute 
  the mass flow rate through the valve section for various valve lifts. Using 
  continuity equation for steady one-dimensional flow, mass flow rate through 
  the valve section is calculated analytically. Effective flow area in terms of 
  lift is obtained experimentally taking the design parameters like flow rate, 
  discharge coefficient, area of cross section and static pressure across the 
  valve section. The effective flow areas are higher at 60% of the valve lift 
  in case of back flow conditions. These experimental results were compared with 
  the analytical values with 5% variation, well with in the accepted limits. These 
  results would be useful in optimizing the performance of reciprocating compressors.}
