... and short channel lengths alongside high solid cross section to fluid free flow area make them susceptible to intense axial conduction loss. The conventional models for macrodevices based on the one-dimensional energy equation are often inappropriate in the microdomain. A novel multidimensional analytical...

... distance from the entrance, m m · = mass flow rate, kg/s Nu k0 = Nusselt number without axial conduction, dimensionless Nu th = theoretical Nusselt number, dimensionless Nu x = local Nusselt number, dimensionless Pr = Prandtl number, dimensionless Re...

...Ting-Yu Lin; Satish G. Kandlikar A model is developed to analyze the effect of axial conduction on heat transfer during single-phase flow in microchannels. The axial heat conduction in the wall introduces heat flow toward the inlet section resulting in an increase in the local fluid temperature...

...M. J. White; G. F. Nellis; S. A. Klein; W. Zhu; Y. Gianchandani Cryogenic and high-temperature systems often require compact heat exchangers with a high resistance to axial conduction in order to control the heat transfer induced by axial temperature differences. One attractive design...

... is its side length. The geometrical parameters C l v and C s l are given in the Appendix 0 . The dimensionless mass flow rate m ̂ (see Eqs. 24 , 25 ) is readily obtained by considering the energy conservation of the liquid phase. Ignoring the axial conduction...

...A. Haji-Sheikh This study uses a methodology based on the calculus of variation to determine the heat transfer in passages with two-dimensional velocity fields such as rectangular channels and in the presence of axial conduction. The mathematical procedure is presented and the subsequent numerical...

...I. Ghosh; S. K. Sarangi; P. K. Das The effect of axial conduction through heat exchanger matrix, heat exchange with the surroundings, and variable fluid properties are included in the simulation algorithm of multistream plate fin heat exchangers. The procedure involves partitioning of the exchanger...
