Heat Transfer

Optimizing heat transfer between fluids and solids is critical in many types of industrial equipment. Examples include pre-heaters, economizers and inter-coolers used in power generation; cooling of turbine blades, engine blocks and cylinder heads, and heating or cooling to control reaction rates in chemical reactors and reformers.

Conventional heat transfer analysis is often limited by dependence on correlations which are valid only for specific types of equipment and operating ranges. Such correlations, where applicable, provide information only on global performance. To truly optimize a design, detailed local behavior must also be understood.

ANSYS CFX features the latest technology for solving fluid flows in 3-D domains including conjugate heat transfer for calculation of thermal conduction through solid materials. CHT can be calculated with mismatched grids at fluid-solid interfaces.
