Webb14 apr. 2024 · Copper heat sinks are better suited for applications that require fast heat transfer and high thermal conductivity. Aluminum heat sinks are better suited for applications that require moderate ... Two types of convective heat transfer may be distinguished: • Free or natural convection: when fluid motion is caused by buoyancy forces that result from the density variations due to variations of thermal ±temperature in the fluid. In the absence of an internal source, when the fluid is in contact with a hot surface, its molecules separate and scatter, causing the fluid to be less d…
WebbHeat energy transferred between a surface and a moving fluid with different temperatures - is known as convection. In reality this is a combination of diffusion and bulk motion of molecules. Near the surface …
