We have introduced a number of new capabilities for this purpose.

In the latest version of COMSOL Multiphysics, it is easier to define and solve problems involving natural convection. In this context, mathematical modeling is the perfect tool. In all of the cases mentioned above, it is important for engineers and scientists to understand and design systems to control natural convection. Environmental sciences and meteorology also involve natural convection problems, as scientists and engineers try to predict and understand transport in air and water. Less obvious natural convection problems are found in industries such as chemical and food processing. The animation shows the value of the velocity in the air around the heat sink. Electronic devices that need to operate in quiet environments often rely on natural convection to circulate air over their built-in heat sinks.ДЇree convection around a splayed pin fin heat sink that is heated from below. For example, we do not want to use noisy fans to cool the amplifiers and TVs in home cinema systems.

In this scenario, hot air rises to the ceiling close to heat sources and cool air sinks to the floor close to cold surfaces, such as the windows during winter.Д®lectronics cooling is another type of process that often depends on natural convection in order to work. You may be familiar with the concept of natural convection in indoor climate systems. This buoyancy is in turn caused by the fluidвЂ™s variations in density with temperature or composition. Natural convection is a type of transport that is induced by buoyancy in a fluid. In this blog post, we give an overview of natural convection, the new functionality, and some of the difficulties that we may stumble upon when modeling natural convection.

The CFD and Heat Transfer modules in version 5.2a of the COMSOL MultiphysicsВ® software include functionality that makes it easier to set up and solve natural convection problems. Natural convection is a phenomenon found in many science and engineering applications, such as electronics cooling, indoor climate systems, and environmental transport problems.
