Heat is a fundamental physical phenomenon that directly affects the performance of a system. Overheating, insufficient cooling, or uncontrolled heat distribution can lead to system failures, reduced product lifespan, and decreased energy efficiency. Therefore, heat transfer analysis is a critical need in engineering.
At this point, one of the most widely used engineering simulation tools in the industry, Ansys, allows you to analyze the thermal behavior of systems in a detailed and accurate way. This process is broadly called Ansys Heat Transfer Analysis.
Ansys Heat Transfer Analysis is a type of simulation performed within various Ansys modules such as Fluent, Mechanical, Icepak, and CFX. This analysis calculates temperature distribution, heat flux, and energy transfer in solid, liquid, or gas systems through three primary mechanisms:
Heat Transfer Mechanisms:
These mechanisms can be modeled individually or in combination within Ansys.
