... of experiments on total heat transfer and short-circuit heat transfer, the Nusselt number can be calculated. The pressure drop across a bayonet tube determined the friction factor. In examining a range of Reynolds numbers, Effectiveness and figure of merit have been resolved. It has been observed...

.... Effectiveness of the ribs ( ε rib ) and critical Rayleigh numbers (Ra cr ), corresponding to ε rib = 1, are also calculated. Ribs are more effective in heat dissipation at low Ra and P/D and high R/D. A correlation for the average Nusselt number is also developed in this work, which would help design a better...

...Milad Kelidari; Ali Jabari Moghadam; Houman Moradi Dalvand The effects of nanoferrofluids on the overall performance of curved tubes (with various radii of curvature) are experimentally investigated under the influence of constant and alternating magnetic fields. The working fluids are distilled...

.... New thermophysical property models have been proposed for hybrid nanofluids with different particle shapes and mixture ratio. Effects of power input, loop diameter, loop height, loop inclination and heater/cooler inclination on steady-state mass flow rate, effectiveness, and entropy generation...

... to evaluate the effects of inlet Reynolds number, Brownian motion, and volume fraction of nanoparticles on the pumping power, effectiveness, and performance index of CFMCHE. The accuracy of the code has been verified by comparing the results with those available in the literature. A single phase approach...

... methodology is based on the arbitrary-Lagrangian-Eulerian method. Computations were performed to find the effects of capacity ratio, channel height, and length on the heat transfer characteristics of micro-heat exchangers. To results are presented in the form of temperature contours, bulk temperatures, total...

... and particle streams, are presented. Measured temperatures, pressures, and overall heat transfer rates are compared to predicted values from a one-dimensional analytical model, and the capabilities and deficiencies of the model are discussed. In addition, the effect of a particle distributor on the performance...
