WebWhen heat is added to a fluid and the fluid density varies with temperature, a flow can be induced due to the force of gravity acting on the density variations. Such buoyancy-driven flows are termed natural-convection (or mixed-convection ) flows and can be modeled by ANSYS FLUENT. For more information about the theory behind natural convection.

WebNatural Convection Between Parallel Plates — Lesson 4. In the previous lesson, we looked at the natural convection heat transfer characteristics of flat plates. For heat transfer analysis of real-world applications such as stacked memory sticks, like the ones shown in the figure below, printed circuit boards inside electronics components, or radiators using large parallel fins, these systems can be approximated as multiple flat plates parallel to each other creating flow channels.

WebNatural, or free, convection of an air mass can be observed, for example, in a coastal region during a summer day when the sun heats up the land and the water. Water takes longer to warm up than land. As a result, the air above the land heats up faster, becomes less dense and rises under the buoyancy force. It is then replaced by the cooler and denser air from the sea, thus resulting in the circular air motion pattern producing a sea breeze.

WebForced convection heat transfer refers to a process in which fluid flow generated by external means, such as a fan or an externally imposed pressure gradient, extracts or imparts heat from or to objects at temperatures different from the flow temperatures. Forced convection.

WebAs the temperature of the fluid near the cylindrical element increases, its density decreases compared to the fluid farther away from the heating element. This density gradient is responsible for moving the hotter fluid to the top and the cooler fluid to the bottom, establishing natural convection.
