Characterization of 3D metal printed cutting tool with transpiration cooling channels
Materials Research Express, 2023 This study characterizes the 3D-printed transpiration cooling (TC) channels in a single-point cutting tool to enhance lubrication and cooling at the cutting zones. Five different TC channels, namely two circular profiled channels (Designs 1-A & 1-B), two

Transpiration cooling of a hypersonic vehicle
, 2021 In this thesis, a porous Ultra-High-Temperature-Ceramic (UHTC) made of zirconium diboride (ZrB2) is qualified for the purpose for transpiration cooling for the first time. Subsequently, the mixing mechanism between the coolant and a laminar, hypersonic boundary-layer gas at the wall downstream of a transpiration-cooled injector is investigated.

Effect of slip condition on vertical channel flow in the presence of radiation
International Journal of Applied Mechanics and Engineering, 2016 An analysis is made on the three dimensional flow of a viscous incompressible fluid through a vertical channel in the presence of radiation in slip flow regime. The right plate is subjected to an uniform injection and the left plate to a periodic suction
