EXPERIMENTAL-STUDY(1991-04-01) ;YAN, WM ;LIN, TF ;TSAY, YL ;交大名義發表機械工程學系An experimental study is performed to study the evaporative cooling of the falling liquid film through interfacial heat and mass transfer in a vertical channel. The measured wall temperature, heat and mass transfer rates are specifically presented for the systems with water film evaporation and ethanol film evaporation over wide ranges of liquid mass flow rate, channel width and liquid inlet temperature. The results show that the influences of the evaporative latent heat transfer on the cooling of the liquid film depend largely on the inlet liquid film temperature and liquid mass rate. Effective evaporative cooling results for a higher inlet liquid film temperature and a smaller liquid mass flow rate.Item type:Item, EVAPORATIVE COOLING OF LIQUID-FILM THROUGH INTERFACIAL HEAT AND MASS-TRANSFER IN A VERTICAL CHANNEL .2. NUMERICAL STUDY(1991-04-01) ;YAN, WM ;LIN, TF ;交大名義發表 ;機械工程學系National Chiao Tung UniversityA numerical analysis is carried out to investigate the evaporative cooling of liquid falling film through interfacial heat and mass transfer in natural convection channel flows. Results for heat and mass transfer rates are specifically presented for the systems with ethanol film evaporation. The predicted results are also contrasted with the experimental results. The predictions show that the effects of the evaporative latent heat transfer on the cooling of the liquid film depend largely on the inlet liquid film temperature and liquid mass flow rate. Additionally, the results indicate that the heat transfer from the interface to the gas stream is predominated by the transport of the latent heat in conjunction with the liquid film evaporation.Item type:Item, HEAT-TRANSFER IN BUOYANCY-DRIVEN CHANNEL FLOWS WITH THE SIMULTANEOUS PRESENCE OF LAMINAR, TRANSITIONAL AND TURBULENT-FLOW REGIMES(1989) ;YAN, WM ;LIN, TF ;交大名義發表 ;機械工程學系National Chiao Tung UniversityItem type:Item, NATURAL-CONVECTION FLOWS IN A VERTICAL, OPEN TUBE RESULTING FROM COMBINED BUOYANCY EFFECTS OF THERMAL AND MASS DIFFUSION(1986-10-01) ;CHANG, CJ ;LIN, TF ;YAN, WM ;機械工程學系Department of Mechanical EngineeringItem type:Item, NATURAL-CONVECTION HEAT-TRANSFER ENHANCEMENT THROUGH LATENT-HEAT TRANSPORT IN VERTICAL PARALLEL PLATE CHANNEL FLOWS(1990-06-01) ;YAN, WM ;LIN, TF ;交大名義發表 ;機械工程學系National Chiao Tung UniversityItem type:Item, NATURAL-CONVECTION HEAT-TRANSFER IN VERTICAL OPEN CHANNEL FLOWS WITH DISCRETE HEATING(1987-03-01) ;YAN, WM ;LIN, TF ;交大名義發表 ;機械工程學系National Chiao Tung UniversityItem type:Item, SIMULTANEOUS HEAT AND MASS-TRANSFER IN LAMINAR MIXED CONVECTION FLOWS BETWEEN VERTICAL PARALLEL PLATES WITH ASYMMETRIC HEATING(1989-09-01) ;YAN, WM ;TSAY, YL ;LIN, TF ;交大名義發表機械工程學系Item type:Item, STEADY CONJUGATE HEAT-TRANSFER IN TURBULENT CHANNEL FLOWS(1990) ;YAN, WM ;FIN, TF ;LEE, TL ;機械工程學系Department of Mechanical EngineeringItem type:Item, THEORETICAL AND EXPERIMENTAL-STUDY OF NATURAL-CONVECTION PIPE FLOWS AT HIGH RAYLEIGH NUMBER(1991-01-01) ;YAN, WM ;LIN, TF ;交大名義發表 ;機械工程學系National Chiao Tung UniversityA combined theoretical and experimental study is performed to investigate natural convection pipe flows at high Rayleigh number. The wall conduction effects and thermal property variations of the fluid and pipe wall are also considered in the analysis. A low-Reynolds-number k-epsilon turbulence model is employed to treat the transitional and turbulent flow regime including buoyancy effects. The predicted and measured distributions of wall temperature and Nusselt number are in good agreement. Empirical correlations for the induced flow rate and average Nusselt number are proposed. Results show that the characteristics of natural convection heat transfer in a vertical pipe approach those along a single vertical plate for large Rayleigh number.Item type:Item, TRANSIENT CONJUGATED HEAT-TRANSFER IN LAMINAR PIPE FLOWS(1989-04-01) ;YAN, WM ;TSAY, YL ;LIN, TF ;交大名義發表機械工程學系Item type:Item, TRANSIENT LAMINAR MIXED CONVECTIVE HEAT-TRANSFER IN A VERTICAL FLAT DUCT(1991-05-01) ;LIN, TF ;YIN, CP ;YAN, WM ;機械工程學系Department of Mechanical EngineeringUnsteady laminar aiding and opposing mixed convection heat transfer in a vertical flat duct is numerically investigated for an initially fully developed flow. Results indicate that unsteady heat transfer characteristics in the flow are principally determined by wall-to-fluid heat capacity ratios. Effects of the buoyancy and degree of asymmetric heating or cooling are rather insignificant. Correlation equations for the time variations of local Nusselt numbers with wall-to-fluid heat capacity ratios are proposed.Item type:Item, UNSTEADY CONJUGATED HEAT-TRANSFER IN LAMINAR PIPE FLOWS WITH STEP CHANGE IN AMBIENT-TEMPERATURE(1987-11-01) ;YAN, WM ;LIN, TF ;交大名義發表 ;機械工程學系National Chiao Tung University
