Experimental Verification of Theoretical Models to Calculate the Heat Transfer Coefficient in the Shell-and-Tube Heat Exchanger

Popis výsledku v původním jazyce

This paper experimentally verifies the validity of theoretical models to calculate the heat transfer coefficient in shell and tube heat exchangers. Determination of the HTC is complex problem, a large deviation in comparison theoretical models and experiments commonly occur. The methods by Kern, Bell-Delaware and Stream-flow analysis method for evaluation of HTC in a vertical shell and tube condenser are compared with results of measurements in the range of Reynolds number from 1200 to 6300. The HTC values by the Kern method reach the top boundary of the experimental results while the results of the Bell-Delaware method and the Stream-flow analysis method lay on the bottom of them. Therefore, usage of the Bell-Delaware method and the Stream-flow analysis method is suitable in accordance with the design assurance.
