APA’s CFD services encompass different convection analysis, to obtain a detailed airflow at the microscopic level. Natural convection occurs as a result of buoyancy-driven flow caused by density gradients due to temperature variations. And it is a very important mechanism that is operative in a variety of environments from cooling electronic circuit boards in computers, cooling of reactor cores in nuclear power plant, Heat loss from steam pipe lines in power plants and heat gain in refrigerant pipe lines in air conditioning applications. Natural convection within a sealed device is considered Internal and around a device in a large enclosure or open environment is considered External. Natural convection flows may be laminar or turbulent.

Forced convection analysis refer to type of heat transfer in which fluid motion is generated by an external source like pump, fans, suction devices and it is considered as the main method of useful heat transfer, as significant amount of heat energy can be transferred by this process. Forced convection is typically used to increase the rate of heat exchange. Forced convection is often encountered for designing or analyzing pipe flow, flow over a plate, heat exchanger, Computer case cooling and so on.
