Experimental Study of Impingement Effusion Cooled Double-Wall Combustor Liners: Aerodynamic Analysis with Stereo-PIV
A new experimental study is presented for a combustor with a double-wall cooling design.The inner wall at the hot gas side features effusion cooling with 7-7-7 laidback fan-shaped holes, and the outer wall at the cold side features an impingement hole pattern with Machines DIY circular holes.Data are acquired to asses the thermal and aerodynamic be
