| Abstract: | The properties of heat transfer and flow resistance in helical baffled orifice plate supported by tubular heat exchanger are analyzed and the correlation equations for the coefficients of heat transfer and flow resistance in the shell side are presented. The flow resistance and the local heat transfer coefficient of rotating flow along radial direction have been measured in the heat exchanger models. Smooth tube bundle and triangle fin tube bundle are included. |
