CFD analyses, including - in particular - flow, heat transfer, and chemical reactions, are becoming the tool, which can improve both parameters of the equipment, and proper understanding of its function.
The combination of numerical methods, classical analytical calculations, and experiments is very effective, and in many cases also indispensable. In certain cases, these calculation methods can reduce the frequency of experiments or can even substitute such experiments for cases where an experiment or measurement is problematic or impossible.
Furthermore, an active role of the customer from the point of delivery of relevant data to assign geometry of the calculation domain (drawing documentation), specification of boundary conditions such as temperatures, pressures, flows (measurement data), operating media (composition of gases, pulverized coal quality), etc. is also essential to prepare CFD analysis of the existing equipment. All too often, delivered data are not consistent, either based on the fact that gauges have not been calibrated or have been installed at an inappropriate point, or not all quantities have been measured at one time. The quality and quantity of measured operating values significantly influence the quality of results.
