WebDescription Project Description. An impinging jet is a fluid jet that strikes a surface vertically or at a specific angle for cooling or heating. In this case, the post-impact flow develops on the surface, creating a thermal boundary layer. As it moves in a peripheral direction, the thickness of this boundary layer increases, and consequently, the rate of heat transfer … Web56 minutes ago · JOINT BASE SAN ANTONIO-LACKLAND, Texas — Two years after a Japanese air force pilot and his American instructor died in a military jet crash in Alabama, officials are mulling whether a U.S.-run ...
