Note (General): Investigation of the jets flowing from air entry holes of the combustor liner of a gas turbine was carried out following the previous experiments using simplified models. Cold air was supplied through the air entry holes normally into the primary hot-gas flows. The mass flow of the primary hot-gas and issuing jets were measured, and the behavior of the air-jets was studied by the measurement of the temperature distribution of the gas mixture. The air-jets flowing from three circular air entry holes being parallel to the primary flow, single streamwise-long holes and two opposing circular holes were studied. The effects of jet and gas stream velocities and of gas temperature, together with these different configurations, were investigated. The discharge coefficient, the maximum penetration of the jets, the jet flow path, the mixing of the jets, and temperature distribution across the jets were investigated. Empirical expressions which describe the characteristics of the jets under the conditions of the experiments were formulated. The experimental results were compared with the results given by a standard circular hole and their characteristics were discussed.
