AbstractA novel three-dimensional thermal model is proposed to study the transient temperature distributions during friction stir welding of aluminium alloys. The moving heat source engendered by rotation and linear traverse pin tool has been correlated with actual machine power input. This power, obtained from experimental investigation, distributed different interfaces formed between weldpiece based on torques generated at surfaces. Temperature dependent properties weld material have used...

Increase in the heat transfer rate during melting and freezing of a phase change material (PCM) with low thermal conductivity is demonstrated by inserting high-porosity metal matrix into PCM. A vertical annulus space (r 1rr 0, 0zh)homogeneously fitted water an aluminum matrix, selected for this study. The Navier-Stokes equations are modified to account Darcy's effect. For both cases, density inversion phenomenon considered. irregularity time-varying nature solid liquid regions accounted...
Aluminium alloy 7050 was friction stir welded using three different ratios of tool rotation rate to weld travel speed. Welds were made speeds between 0·85 and 5·1 mm s −1 . Weld power torque recorded for each weld. An FEM simulation used calculate the time–temperature history a subset welds. For hardness distribution with without post-weld heat treatment determined. The distributions within welds are rationalised based on welding parameters resulting temperature histories. analysis provides...
In a microchannel system, higher mass velocity can lead to enhanced flow boiling performances, but at cost of two-phase pressure drop. It is highly desirable achieve high heat transfer rate and critical flux (CHF) exceeding 1 kW/cm2 without elevating the drop, particularly, reduced velocity. this study, we developed configuration that enables more efficient utilization coolant through integrating multiple microscale nozzles connected auxiliary channels as well reentry cavities on sidewalls...
