Numerical investigations are conducted to study the effect of factors such as particle clustering and interfacial layer thickness on thermal conductivity of nanofluids. Based on this, parameters inclu...
Scaling laws prediction from a solvable model of turbulent thermal convection
Turbulent flows, convection and heat transfer Turbulence simulation and modeling
2011/8/31
A solvable turbulent model is used to predict both the structure of the boundary layer and the scaling laws in thermal convection. The transport of heat depends on the interplay between the thermal, v...
Scaling in large Prandtl number turbulent thermal convection
Turbulent fiows convection and heat transfer Turbulence simulation and modeling
2011/9/13
We study the scaling properties of heat transfer Nu in turbulent thermal convection at large Prandtl number Pr using a quasi-linear theory. We show that two regimes arise, depending on the Reynolds nu...

Thermal wall influence on the behavior of axisymmetric laminar compressible flow in nozzle
compressible Mac-Cormack scheme nozzle numerical study viscous flow wall
2010/3/11
The present work concerns a numerical study of an axisymmetric laminar flow of a compressible gas in a small size convergent-divergent nozzle. The geometry and the reservoir conditions are such that t...
Application of generalized FDM for numerical solution of non linear thermal diffusion problems
generalized finite difference method non-linear thermal diffusion
2010/3/12
A generalized variant of the finite difference method [2, 3, 4] is used for numerical modelling of non-steady and non-linear thermal diffusion problems. In order to simplify the considerations the 1D ...
