| Description
| - Research of devices for heat recovery are currently focused on increasing the temperature and heat efficiency of plate heat exchangers. The goal of optimization is not only to increase the heat transfer or even moisture but also reduce the pressure loss and possibly material costs. During the optimization of plate heat exchangers using CFD, we are struggling with the problem of how to create a quality computational mesh inside complex and irregular channels. These channels are formed by combining individual 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 later optimization. The paper presents a method of creating meshes based on dynamic mesh method provided by software Fluent. Creating of mesh by pulling is similar to the own production process, i.e. it is perpendicular to the plates. The advantages of this method are: The ability to change quickly the whole geometry of the plate, possibility to use optimization algorithms, ability to control the size of the wall adjacent cells and similarity of meshes even in completely different geometries. The paper discusses the problems with very narrow gaps and distortions of the mesh. Using this method, a row of cases with waves and ridges were created. The resulting dependence of efficiency and pressure loss on the ridges count are replaced by mathematical relationships. An objective function is suggested and verified to optimize heat transfer surface of the exchanger.
