Abstracts:
Results of development and numerical research of thermal protection of the surfaces streamlined by a disperse working fluid on the example of blades of turbomachines are given. The possibility of increase in accuracy of settlement forecasting of a thermal condition of blades due to obtain of reliable data by development of mathematical model and a unique complex of programs for modeling is shown. Opportunities and conditions of increase in efficiency of chilling of turbine blades by using damping cavities are researched. |
