HEAT TRANSFER AND FLUID FRICTION DURING FLOW ACROSS BANKS OF TUBES. VII. BYPASSING BETWEEN TUBE BUNDLE AND SHELL
Results were reported on the pressure drop and rate of heat transfer during flow across tube banks and for flow on the shell side of a cylindrical, baffled heat exchanger with and without appreciable internal leakage across the baffle. A method was proposed for predicting the performance on the shell side of baffled exchangers from the cross-flow data from rectangular tube banks and baffle-leakage coefficients. Information on the flow between the outer row of tubes and the shell wall in rectangular tube banks is presented. The results presented include isothermal, heating, and cooling runs in both the laminar and turbulent regimes for two tube-bank geometries with various bank-to-shell clearances. The effect of sealing strips to block the bypass stream is shown. Methods of generalizing the results for commercial exchanger design are considered. (auth)
