... of a binary and a ternary mixture was also investigated. These mixtures were C 1 (methane)/n-C 4 (normal-butane) and C 1 (methane)/C 2 (ethane)/n-C 4 (normal-butane), which were under diffusion and natural convection. Governing equations were numerically solved using matlab . One of the main relevant...

... considered, the parametric dependence of key performance measures is shown to be expressible in terms of a Peclet number and a Froude number or temperature difference ratio. The thermal mixing factor for each of the models is reasonably well described by a power law fit with Fr 2 Pe for the convection...

...Matthew G. Sutton; Darin W. Nutter; Rick J. Couvillion A new ground resistance was developed for use in existing vertical bore heat exchanger VBHE x design algorithms. The new ground resistance accounts for the added heat transfer mode of convection due to groundwater flow by using as its...

.... The variation of the thickness of the wall layer along the height direction is considered in the fluid dynamic model in order to approach the practical conditions. Three components of heat transfer, i.e., the particle-convective heat transfer, the gas-convective heat transfer, and the radiative heat transfer...

... the heat losses were attributed to the increased heat convection within the porous insulation medium. Recognizing loose spaces between half-shells may contribute to the dramatic heat losses, the authors from R. J. Brown Deepwater conducted a new set of tests that used the same open-cell foam material...
