![]() The laminarity of the flow allows to assume that there is no lateral disruption between layers of the fluid, therefore radial velocity components can be omitted. The case under investigation is a fully developed, pressure-driven laminar pipe flow, also known as the Hagen-Poiseuille flow. The latter occurs when the fluid is forced to move by an external source such as a ventilator and this mechanism of heat transfer, due to its importance in engineering applications, is going to be the centerpiece of today’s article. motion of a fluid in a cup heated at its bottom. The former takes place when the fluid’s motion is driven by buoyancy, that is an upthrust caused by a non-equilibrium state of gravitational forces, e.g. Depending on the nature of this process, convection can be divided into two types – natural (free) convection and forced convection. Convection occurs when heat is transferred within a fluid by means of motion. The transfer of heat can take place by one of three mechanisms – convection, conduction or radiation. The objective of today’s article is to present the fundamental principles of forced convection and to validate our QuickerSim CFD Toolbox against an analytical solution of a fully developed laminar pipe flow with constant flux value heat transfer. Numerical simulation of heating and cooling processes, if properly conducted, reduces development costs, improves safety and underlies optimization. Heat transfer is a process that is abundant in nature and extensively used for engineering applications, therefore a good understanding of the phenomenon allows to tackle various scientific and technological problems.
