Forced convection boiling of non-azeotropic mixtures.

Forced Convection Subcooled Boiling of Binary Mixtures

A mode based on an additive mechanism of heat transfer is proposed for forced convection subcooled boiling of binary mixtures. The contributing modes of heat transfer are: (i) the heat transferred as latent heat by the rising bubbles, (ii) the heat transferred as the heat contained in the superheated thermal layer that is removed from the surface in the wake of the rising bubbles and (iii) the ...

Prediction of bubble departure in forced convection boiling: A mechanistic

Performance of Reciprocating Compressors with Non-Azeotropic Mixtures

Performance of a reciprocating refrigerator compressor with mixed-refrigerants (MR) was investigated experimentally. The current, standard methods of testing compressors and presenting performance data were found unsuitable for MR, and a new experimental apparatus was designed for a ·direct flowrate measurement with MR. Representative test data for Refrigerant R-12 and for a mixture of R-22/R-1...

Forced-convection boiling and critical heat flux from a linear array of discrete heat sources

Forced-convection boiling experiments were performed with FC-72, a 3M Fluorinert, at 1.36 bar on a linear array of nine discrete heat sources simulating microelectronic chips, which were flushmounted in a vertical. rectangular channel. The inlet velocity and liquid subcooling were varied from 13 to 400 cm s’ and 3 to 36”C, respectively. Special design of the experimental apparatus allowed each ...

Forced Convection Heat Transfer of Non-Newtonian Fluids Through Circular Ducts

The Galerkin finite element method is used to solve the three dimensional continuity, momentum and energy equations for laminar Newtonian and power-law model non-Newtonian flow through horizontal circular tube. The governing equations are non-dimensionalized with respect to specific variables and converted into algebraic equations using appropriate elements. To accelerate convergence a combinat...
