Currently one of the urgent problems of modern engineering practice is the problem of fuel efficiency. One of the solutions of this problem is to using the heat recovery. The key technology in this case is the heat exchanger (HE). One of the most important components of the designing of the HE is the method of a calculation and design. The purposes of the study are: development and verification the three-dimensional calculation method of the HE; development of the analytical evaluation program of calculation, on the basis of the criterion of dependencies from the three-dimensional calculation method; development of the parametric 3D-models of the HE plate and tools for its manufacturing.
In the study, the three-dimensional calculation and design method were developed and described. Development of parametric 3D-models and tools helps to reduce the time of design and preparing the calculation model. The test to verify three-dimensional calculation method was carried out. The verification of the method, basing on the test data, and additional verification, basing on criteria dependencies were performed. As part of the verification a structured hex-mesh and an automatic tetra-mesh were considered. In the frame of practical work the most convenient option of the mesh was chosen. Basing on the three-dimensional calculation research the evaluated analytical program was developed. This program is used to obtain a preliminary assessment of the heat transfer surface with given geometric parameters and operating modes of HE.Considered method is used to obtain a preliminary assessment of the heat transfer surface with the specified geometric parameters and operating modes of the heat exchanger. This allows reducing development time and cost of full-scale tests.
