Abstract


The plate heat exchanger is a compact and efficient heat transfer equipment , its application is related to almost all industrial areas , and the type , structure and use are still evolving . In recent years , the type welded plate heat exchanger , compact , light weight , good heat transfer performance , low initial cost superiority has increasingly been recognized , so people have on the state of the plate heat exchanger flow and change thermal mechanism study . CFD (Computational Fluid Dynamics) technology becomes increasingly sophisticated , the distribution of the the fluid internal temperature field , pressure field and velocity field feasible In view of this , the application of CFD numerical simulation software herringbone corrugated plate heat exchanger based on a comparative analysis of the experimental study and the experimental data and numerical simulation . Specific conduct of the work of the following four aspects : (1 ) based on the flow of plate heat exchangers and heat transfer mechanism , the use of commercial CFD software FLUENT build a herringbone corrugated plate heat exchanger calculation model and meshing by thermodynamics and fluid the mechanical analysis of the complete set of boundary conditions as well as the selection of the turbulence model ; (2) of the geometric parameters of the the different corrugated inclination β, corrugation depth h , corrugated spacing λ plate heat exchanger to simulate the temperature field, pressure field , speed the field , and the use of the calculation results fit geometric parameters of the Nusselt number Nu, the relationship between the pressure drop Δp curve . Conclusion literature concluded verify the accuracy of the numerical model ; ( 3) to design and build a plate heat exchanger water - water heat exchanger test system , the fluid temperature and flow into the heat exchanger by changing experimental data for a range of different operating conditions ; overall calculation model building herringbone corrugated plate heat exchanger (4 ) established numerical calculation model based on the numerical simulation of the specific types of plate heat exchanger , get the plate inside the heat exchanger temperature field, pressure field and velocity field , and to analyze the performance of the plate heat exchanger , while the numerical results with experimental values ??to compare , verify the accuracy of the calculation model .
