چکیده
In order to cool the gas turbine vane or blade and raise operating temperature, two standard convective cooling methods are used: jet impingement film cooling. The current study uses computational analysis analyze compare effectiveness with without multi-jet on a flat plate. Ansys Fluent software is used perform results were compared experimental result using K-ω SST turbulence model validated literature data. plate for conjugate heat transfer hot surface (named interaction surface), cold (called target inside hole. Different parameters such as flux, Nusselt's number, cases, i.e., impinging jets (IFC) (FC). It observed that FC case shows lower IFC case. average Nusselt number cases almost three times larger than FC. exit temperature values higher case, but it more uniform in Interaction flux show upstream wall of hole

Shape optimization of impingement and film cooling holes on a flat plate using a feedforward ANN and GA
Numerical simulations of a three-dimensional model of impingement and film cooling on a flat plate are presented and validated with the available experimental data. Four different turbulence models were utilized for simulation, in which SST had the highest precision, resulting in less than 4% maximum error in temperature estimation. A simplified geometry with periodic boundary conditions is de...
متن کاملFilm Cooling: a Comparative Study of Different Heater- Foilconfigurations for Liquid Crystals Experiments
A new measurement technique for the determination of the heat transfer coefficient and the film cooling effectiveness is presented. It is based on a regression of multiple transient liquid crystals experiments using an electrical heater-foil producing a nonhomogeneous surface heat flux. This is particularly interesting for film-cooled surfaces where each cooling hole in the heater-foil leads to...
متن کاملFilm Cooling Measurements for Novel Hole Configurations
The effect of film cooling slot exit area and shape is studied. Detailed heat transfer coefficient and film effectiveness measurements are obtained simultaneously using a single transient IR thermography technique. Two designs with a crescent shaped exit and a slot exit are considered. The results show that the crescent shaped exit provides significantly higher film cooling effectiveness than t...
