چکیده
Thin liquid wall fillTIs flowing under the influence of high-velocity turbulent gas streaIllS were studied for the purpose of obtaining an understanding of the Illechanics of filIll cooling. Conditions which insure liquid-filIll attachIllent to solid surfaces without loss of unevaporated liquid to the gas streaIll when siIllple radial-hole injectors are used were found; the IllaxiIlluIll allowable coolantflow rate for a stable coolant filIll was deterIllined (a stable coolant filIll is obtained when no unevaporated coolant is entrained by the gas streaIll as the result of interfacial disturbances); and a Illethod for calculating the evaporation rate and the surface teIllperature for a stable inert coolant filIll was found.

Irreversibility Analysis of MHD Buoyancy-Driven Variable Viscosity Liquid Film along an Inclined Heated Plate Convective Cooling
Analysis of intrinsic irreversibility and heat transfer in a buoyancy-driven changeable viscosity liquid along an incline heated wall with convective cooling taking into consideration the heated isothermal and isoflux wall is investigated. By Newton’s law of cooling, we assumed the free surface exchange heat with environment and fluid viscosity is exponentially dependent on temperature. Appropr...
متن کاملExperimental Investigation into the Hydrodynamics Effects of Slot Film Cooling on a Cylindrical Model
An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...
متن کاملAn Innovation in Film Cooling of the Gas Turbine Blades Applying an Upstream Jet
A new design concept is introduced to control the near-wall integration between the hot-gas boundary layer and the cooling jets in order to enhance the adiabatic film cooling effectiveness of the gas turbine blades. In this new approach, another film cooling port, having a very low blowing ratio, which prevents formation of the counter-rotating vortex pare, is applied just upstream of the main ...

متن کاملTowards an Analytical Model for Film Cooling Prediction using Integral Turbulent Boundary layer
The objective of this work is to develop deep theoretical methods that are based on the solution of the integral boundary layer equations for investigating film cooling in liquid rocket engine. The integral model assumes that heat is transferred from hot free stream gas to the liquid film both by convection and radiation. The mass is transferred to the free srteam gas by the well-known blowing ...
