Modern gas turbines work under demanding high temperatures, high pressures, and high
rotational speeds. In order to ensure durable and reliable operation, effective cooling …

This paper summarizes experimental and computational results on the mixing of single,
double, and opposed rows of jets with an isothermal or variable temperature mainstream in …

Film-cooling effectiveness was studied using a row of inclined holes that injected
cryogenically cooled air across a flat, adiabatic test plate. The density ratio of the coolant to …

A previously documented systematic computational methodology is implemented and
applied to a jet-in-crossflow problem in order to document all of the pertinent flow physics …

Numerical results are presented for a three-dimensional discrete-jet in crossflow problem
typical of a realistic film-cooling application in gas turbines. Key aspects of the study …

This paper describes the application of a three-dimensional finite difference procedure to the
analysis of the flow and thermal (or concentration) fields created by the injection of fluid …

Some of the work at Detroit Diesel Allison (DDA) that has been aimed at the synthesis,
characterization, and evaluation of a promising porous wall combustor-cooling concept …

Large-eddy simulations of a generic turbulent flow with discrete effusion are reported. The
computational domain is periodic in both streamwise and spanwise directions and contains …

A jet stream entering a crossflow is investigated for injection through a single hole and an
array of holes for blowing rates of 0.2 to 2.2. The naphthalene sublimation technique has …

IN GAS turbines, the turbine blades and the liner of the combustion chamber are submitted
to large thermal constraints. As the materials used for these solid parts cannot stand such …
