“…The numerical experiment involved the use of ANES/NE computer codes [7,8] lation of a three-dimensional problem solved using ANES/NE, which is more complete compared to that of the two-dimensional steady-state problem treated by us. In order to define more concretely the boundary-value problem being solved, we will write and discuss the equations and boundary conditions employed by us.…”

Results of numerical experiment are used for analysis of fields of temperature in a laminar boundary layer, in a porous wall, and in a cooling gas delivery chamber, as well as for analysis of heat transfer and of distribution of the temperature difference between the cooling gas and the porous wall frame and cooling efficiency. It is demonstrated that heat transfer between a porous wall of finite thickness and a hightemperature gas flow differs significantly from heat transfer with preassignment of the same intensity of injection and of the homogeneous thermal boundary condition directly on the surface subjected to flow. One of the reasons for this is the formation of wall temperature variable along the boundary layer.

The research era and development on two-phase flow boiling will give a tremendous choice in various application fields. In spite of this progression, there arise disarray forms under the different streams of thecross-section, oblique fins and types of fluid being used. This study deals on various cross-sections such as rectangular, square, triangle and with avariable aspect ratio of themicrochannel. The paper focuses on the behavior of different types of fluid used in amicrochannel with various thermo-physical properties. The formulated growth in the fields of flow boiling from the introductory to the modern changes is enumerated in both the ways of experimental as well as numerical. In addition to that, this paper concerns the bubble growth rate and heat transfer characteristics of flow boiling experiments. Numerical solutions and their correlations with their experimental data are also summarised. The stimulated improvements in various aspects of microchannel era in experimental and theoretical dataare tabulated. Based on the consolidated database a new model approach on two-phase flow boiling has resulted out.
