Forced Convection
A forced convection heat transfer capability is available in ALGOR's steady-state and transient heat transfer analysis products to consider the effects of fluid flow when solving for temperature distribution. For example, when air is blown over a surface by a fan, it is termed forced convection. In contrast, when flow is induced by the heating of a fluid that would otherwise be motionless, such as the heating of a pot of water on a stove, it is termed natural convection. Both natural and forced convection can occur simultaneously (mixed) in the same application. Engineers can perform a fluid flow analysis and then consider the velocity results as part of a direct convection load in a heat transfer analysis. The heat transfer results specify temperature distribution for both the fluid and solid components in systems such as fan- or water-cooled CPUs and heat exchangers. Other applications for forced convection include systems that operate at extremely high temperatures for functions like transporting molten metal or liquefied plastic. Engineers can determine what fluid flow velocity is necessary to produce the desired temperature distribution and prevent parts of a system from failing. Engineers performing heat transfer analysis can simply click an option to "Include fluid convection effects" and specify the location of the fluid velocity results during setup to yield forced convection heat transfer results. For more information on our forced convection capabilities, see the How to Couple Fluid Flow and Steady-State Heat Transfer for Forced Convection Tech Tip and the ALGOR User's Guide.
