要約

Pillow plate heat exchangers is an assembly of pillow plates having three-dimensional wavy surfaces:w. The pillow plates are generated by hydroforming process applied on plates welded together by spot welding. The complex three-dimensional channel formed inside the channel increases the turbulence in the flow which results in increase heat transfer. The pillow plate heat exchangers can be found in process industries for singlephase as well as multi-phase applications. The present work is focused on the study of turbulent single-phase fluid flow and heat transfer characteristics of the pillow plate channel. The wavy pillow profile of the channel is generated with finite element analysis and validated with the correlations. The Nusselt number obtained from the CFD simulation is validated with the experiments. Further, the hydraulic and thermal development length within the channel is analysed. The flow is fully developed within the length considered for the simulation. The hydraulic development length found to be increasing with increasing Reynolds number of the flow.
