Thermal Analysis and Modeling of Steady-State Rod Growth During Gas-Phase Solid Freeform Fabrication [PDF]

open access: yes, 1993
An analysis ofthe steady-state growth ofrods during gas-phase solidfreeform fabrication is presented. It is demonstrated that heat transfer controls the evolution ofshape during laser-induced pyrolysis of slender 3-D structures.

Subcooled flow boiling in diamond/Cu microchannel heat sinks for near-junction chip cooling

open access: yesCase Studies in Thermal Engineering
Materials for thermal management that possess low coefficient of linear thermal expansion and high thermal conductivity can achieve “near-junction cooling” for chips. However, limited research exists on the application of the latest generation of diamond/

Modelling and Analysis of Plate Heat Exchangers for Flexible District Heating Systems

open access: yesEnergies, 2019
Seamless integration of district heating (DH) and power systems implies their flexible operation, which extends their typical operational boundaries and, thus, affects performance of key components, such as plate heat exchangers (PHXs).

Finite element solution of nonlinear convective flow of Oldroyd-B fluid with Cattaneo-Christov heat flux model over nonlinear stretching sheet with heat generation or absorption

open access: yesPropulsion and Power Research, 2020
In this study, a two-dimensional boundary layer flow of steady incompressible nonlinear convective flow of Oldroyd-B fluid over a nonlinearly stretching sheet with Cattaneo-Christov heat flux model and heat generation or absorption is examined.

Thermocapillary effects in driven dewetting and self-assembly of pulsed laser-irradiated metallic films [PDF]

open access: yes, 2009
In this paper the lubrication-type dynamical model is developed of a molten, pulsed laser-irradiated metallic film. The heat transfer problem that incorporates the absorbed heat from a single beam or interfering beams is solved analytically.

Roughness effects in turbulent forced convection [PDF]

open access: yes, 2018
We conducted direct numerical simulations (DNSs) of turbulent flow over three-dimensional sinusoidal roughness in a channel. A passive scalar is present in the flow with Prandtl number $Pr=0.7$, to study heat transfer by forced convection over this rough
