Computational study of film cooling from single and two staggered rows of novel semi-circular cooling holes including coolant plenum

A synthetic layout optimization of discrete heat sources flush mounted on a laminar flow cooled flat plate based on the constructal law

“…hydrogen supplying for fuel cell [1], gas turbine cooling [2], high-power LED cooling [3,4]. For flow boiling, the heat transfer is mechanistically intertwined with interfacial effect [5], flow pattern [6] and so on and is therefore more vulnerable to drawbacks such as bubble clogging and local superheating [7].…”

Computational prediction into staggered film cooling holes on convex surface of turbine blade

“…They demonstrated that cooling hole shape significantly affects film cooling effectiveness. Asghar and Hyder [3] computationally studied the film cooling for single and two staggered rows of novel semi-circular holes. It could be said that the main finding is that the centerline and lateral effectiveness of the two staggered rows of semi-circular holes are much higher than a single row of full circular hole.…”

Film cooling optimization on leading edge gas turbine blade using differential evolution

“…1 Experimental and numerical investigations have been carried out to study separately the effects of the mentioned parameters. 2–6 Nevertheless, the study of parameters interacting simultaneously to obtain a cooling optimum design is a complicated task and for this reason new computational tools are needed. Recently, optimization methods have been implemented to obtain objective and efficient evaluations of the performance of industrial flows.…”
