Distribution of the number of jobs in a GI/GI/1/∞ queue with a constant flow time constraint

We derive the Laplace transform of the joint distribution density of the number of jobs and of the vector of their flow time in a GI/GI/1/ queue with a constant constraint on job flow time.Translated from Kibernetika, No. 1, pp. 78–81, January–February, 1889.     

Performance of film cooling by injection from a porous section

Results are presented on film cooling by homogeneous injection into a turbulent boundary layer through porous inserts of various lengths along the main flow direction.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 29, No. 5, pp. 793–798, November, 1975.     

Intensification of convective heat exchange in channels with a porous high-thermal-conductivity filler. Heat exchange with local thermal equilibrium inside the permeable matrix

Results are presented from analytical and experimental studies of intensification of convective heat exchange in a channel with a porous high-thermal-conductivity filler in the case of moderate external heating.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 47, No. 1, pp. 13–24, July, 1984.     

Numerical determination of two-dimensional temperature fields in transpiration cooling

We present a numerical method for solving a wide range of transpiration cooling problems.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 47, No. 6, pp. 984–991, December, 1984.     

Initial superheating of a liquid in boiling on a porous surface

A new model of boiling of a liquid on porous surfaces is proposed based on which a dependence for the superheating of the liquid at the beginning of boiling is derived. The effect of regime and structural parameters on the initial superheating is analyzed. The results obtained are compared with experimental data. Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 71, No. 1, pp. 173–175, January–February, 1998.     

Boiling of solutions on porous surfaces

A semiempirical model of heat transfer is suggested for solutions boiling on porous surfaces. In the limiting cases of low and high admixture concentrations at the heating wall, heat transfer is described byq ~⇏ δT ³ andq ⇏ δT ², respectively. Calculated data are compared with the data observed for refrigerants.
