Deep Underground Science and Engineering, EarlyView.Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Review on Key Factors in Closed-loop Pulsating Heat Pipes within Atmospheric Temperature
Zhileng xuebaoA closed-loop pulsating heat pipe within atmospheric temperature relies on the pulsation and phase change of the internal working fluid. It has been widely used for the heat dissipation of electronic components owing to its high heat transfer efficiency,

Energy Science &Engineering, EarlyView.Cuttings transport simulation workflow. ABSTRACT Efficient cuttings transport is essential for wellbore stability and minimizing non‐productive time in deviated and horizontal wells. This study applies global sensitivity analysis (GSA) to evaluate the influence of 14 drilling parameters on cuttings transport using WellPlanTM hydraulic simulations ...

Heat Transfer, EarlyView.ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Thermal Performance of Micro-Pulsating Heat Pipe
International Journal of Engineering and Advanced Technology, 2019 In this study, thermal performance of MPHP is investigated computationally. A case with 0.7mm hydraulic diameter with 7 turns is considered for the study. Simulation is carried out using ANSYS-FLUENT® software by considering water as working fluid with the help of VOF model. Computational study shows the oscillation of fluid inside and formation of new
