Efficient thermal management in compact high-heat-flux systems requires cooling methods that enhance convective heat transfer while limiting additional flow resistance. This study uses COMSOL Multiphysics to investigate transient forced convection in a long straight channel containing an ... En savoir plus

Although conventional Al 7xxx alloys are widely used in aerospace and automotive applications, their LPBF-processed counterparts exhibit poor weldability and susceptibility to solidification cracking. These challenges are partly due to the limited understanding of the melt pool ... En savoir plus

Efficient, stable, and abrupt doping is challenging in semiconductor fabrication, especially in nano-sheet or nano-ribbon transistors. For example, in epitaxial silicon doped above the solubility of phosphorus, most phosphorus dopants are compensated by vacancies. Some of the phosphorus ... En savoir plus

This work presents a multiphysics simulation of a Pirani vacuum gauge using COMSOL Multiphysics. Pirani gauges infer pressure from the pressure dependence of gas thermal conductivity by measuring the steady‑state temperature of a resistively heated filament. Accurate modeling is ... En savoir plus

Chronic dry eye disease can be effectively treated with red light, which has been shown to stimulate and unblock meibomian glands. Designing wearable low-level light therapy (LLLT) devices requires achieving an effective energy dosage while not overheating the surrounding tissue and ... En savoir plus

Plastic waste management remains a critical global challenge due to the continuous increase in polyethylene terephthalate (PET) production and the limitations of conventional recycling methods. Chemical recycling through pyrolysis represents a sustainable alternative for converting PET ... En savoir plus

Lightweight polymeric cellular solids are central to transportation, impact protection, thermal isolation, packaging, soft robotics, and biomedical systems, yet conventional foam manufacturing remains constrained by molds, multistep processing, high external energy demand, and limited ...

Blade-tip clearance and turbine inlet temperature are critical efficiency parameters in turbomachinery design. Smaller clearances reduce leakage losses, but increase the risk of rubs between blades and the casing. Higher operating temperatures improve efficiency, but reduce the finite ... En savoir plus
