- In the present work, the flow boiling heat transfer is experimentally investigated in a small plate heat exchanger with dimensions equal to 0.05*0.025*0.005 m3. The working fluid is n-pentane which is chosen for its low boiling point (36 ° C at atmospheric pressure). The independent variables are velocity in the range from 0.015 m/s to 0.06 m/s and the boiling heat flux with values between 9 and 137 kW/m2. The wall superheat and exit vapor quality are presented as dependent variables. As results, we present a new method to predict the flow pattern on the basis of the temperature fluctuations. In other hand, the comparison with the literature shows a good agreement with Gungor-Winterton and Jens-Lotte correlations.
