Convective Heat Transfer Coefficients in Concentric Annuli
Jaco Dirker,Josua P. Meyer +1 more
TL;DR: In this article, the Wilson plot method was used to develop a convective heat transfer correlation for annular diameter ratios of 17 to 32 for Reynolds numbers (based on the hydraulic diameter), in the range of 4000 to 30000, which predicted Nusselt numbers accurately within 3% of experimental values.
Journal ArticleDOI
Condensation heat transfer in smooth inclined tubes for R134a at different saturation temperatures
TL;DR: In this article, the effects of saturation temperature and inclination angle on convective heat transfer during condensation of R134a in an inclined smooth tube of inner diameter of 8.38mm were investigated.
Journal ArticleDOI
Topology Optimization for an Internal Heat-Conduction Cooling Scheme in a Square Domain for High Heat Flux Applications

Journal ArticleDOI
Three-dimensional conductive heat transfer topology optimisation in a cubic domain for the volume-to-surface problem
TL;DR: In this paper, the authors investigated three-dimensional topology optimisation with regard to heat conduction for the volume-to-point or volume to-surface problem in a cubic 3D domain, where the positioning of high conductive material in a solid with low thermal conductivity and high heat generation was optimized via the method of moving asymptotes (MMA) algorithm.
Journal ArticleDOI
Inlet flow effects in micro-channels in the laminar and transitional regimes on single-phase heat transfer coefficients and friction factors
TL;DR: In this paper, an experimental investigation of heat transfer and pressure drop in rectangular micro-channels was conducted for water in the laminar and transitional regimes for three different inlet configurations.
