RISJet Impingement Heat Transfer Enhancement by Packing High-Porosity Thin Metal Foams Between Jet Exit Plane and Target Surface
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: High-porosity metal foams are known for providing high heat transfer rates, as they provide a significant increase in wetted surface area as well as highly tortuous flow paths resulting in enhanced mixing. Further, jet ...
Effect of Rotation on Heat Transfer in AR = 2:1 and AR = 4:1 Channels Connected by a Series of Crossover Jets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed heat transfer measurements using transient liquid crystal thermography were performed on a novel cooling design covering the mid-chord and trailing edge region of a typical gas turbine blade under stationary and ...
Jet Impingement Heat Transfer Enhancement by U-Shaped Crossflow Diverters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Array-jet impingement is typically used in gas turbine blade near-wall cooling, where high rates of heat dissipation is required. The accumulated crossflow mass flux results in significant reduction in jet effectiveness ...
Array Jet Impingement on High Porosity Thin Metal Foams: Effect of Foam Height, Pore-Density, and Spent Air Crossflow Scheme on Flow Distribution and Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental investigation was carried out to study heat transfer and fluid flow in high porosity (93%) thin metal foams (MFs) subjected to array jet impingement, under maximum and intermediate crossflow exit schemes. ...
