Computational experiment in creating a virtual design system for drum dryerswith a heat pump

One of the effective areas of research of real technological processes is the creation of virtual processes and its components. In the work, virtual computer models have been created that establish a connection between the mathematical model of the drying process and the simulated design of a two–section drum dryer equipped with an absorption water–ammonia heat pump. To simulate the drying process, a mathematical model based on differential equations of heat and mass transfer A.V. Lykov, algorithmic and software of the drying process were used and a single virtual system was created that allows simulating the drying process of cereals, oilseeds and legumes in a drum dryer in real time over a wide range of regime parameters. To conduct a computational experiment in one of the CAD systems, a three–dimensional visualization of a drum dryer was performed and a graphical shell of the LabVIEW environment was used with a set of all the tools necessary for data collection, analysis and presentation of the results obtained. 3D execution of the drum dryer in CAD (computer–aided design system) made it possible to simulate the real conditions of its operation, compare alternative options and select the best design solutions.
