Composite Heat Sink LED Cooling
Metal coating of 3D printed polymers is an attractive proposition for thermal dissipation of light emitting diodes, due to its high efficiency and markedly lower material costs than conventional aluminum heat sinks. Efficient ...
Analytical heat conduction model of annular composite fins
A two-dimensional analytical heat conduction model of an annular composite fin has been carried out. The composite fins composed of a porous polyethylene core, a square aluminum insert, and metallic zinc coating layers, ...
Changes In The Leidenfrost Transition Point During The Evaporation Of Water And N-Heptane Droplets On Hot, Porous Stainless Steel Surfaces
The impact and evaporation of droplets impinging on a heated porous substrate is relevant to applications such as fire suppression by sprinkler systems, spray cooling of heated surfaces, and the deposition of fuel droplets ...
Water Droplet Impact And Spreading On A Narrow Gap
The impact and spreading of a water droplet on a gap between two parallel plates has been studied experimentally. A deionized water droplet (2.03 mm diameter) impacted the plates at velocities of 0.06, 0.5, 1.0, and 1.5 ...
Motion Of Pigments In Thin Paint Films
When thin paint layers are exposed to heat, evaporation of the solvent begins, and significant movement within the paint film occur, causing temperature and concentration gradients. A clear coat paint was used, which had ...
