Advanced methods of modelling and design of plate heat exchangers

Original language description

Research of devices for heat recovery is currently focused on increasing the temperatureand heat efficiency of plate heat exchangers. The goal of optimization is not only to increase the heattransfer but also reduce the pressure loss and possibly material costs. During the optimization of plateheat exchangers using CFD, we are struggling with the problem of how to create a qualitycomputational mesh inside complex and irregular channels. These channels are formed by combiningindividual plates or blades that are shaped by molding, vacuum forming, or similar technology.Creating computational mesh from the bottom up manually is time consuming and does not help lateroptimization. The paper presents a new method for creating of computational meshes to simulateflow and heat transfer in a plate heat exchanger. This method is based on dynamic mesh method “userdefined deforming” provided by ANSYS Fluent. The method is fast and provide applicable tool foroptimization. Influences of cell size and count of layers of computational cells on heat transfer andpressure drop were investigated. It was found that the minimum number of layers is twelve across thechannel, otherwise obtained data can be irrelevant. The optimal size of computational cells was notfound, but it seems that as smaller cells as possible yield the best agreement with experiments.
