This study aims at the design and optimization of a Gas Sensing Chamber. The design takes advantage of the multiphysics simulation capabilities of COMSOL Multiphysics® to incorporate various physics such as CFD, Micro fluidics, Solid Mechanics, Electro thermal effects etc. The optimization needs to be done at multiple levels such as mixture of two gases, arriving laminar flow over the substrate, ...

Liquid metals are foreseen as a multipurpose coolant in fusion blanket systems. However, the strongly magnetic environment of the fusion reactor hinders the regular flow of the liquid metal. It interacts with transverse magnetic field and produces a Lorentz force opposing the flow, modifying the regular flow profile in the circular pipe or rectangular ducts. Complex geometry and lack of ...

In this work, we study the design of a new integrated system for Solar Water Heating that combines the solar thermal energy collection (primary circuit) with the heat storage (secondary circuit) into the same device. We have performed different finite element method simulations using COMSOL Multiphysics®, for solving the equations of heat transfer (conduction and convection) and those of fluid ...

In certain cases, the accuracy of measurements with a rotational rheometer can be influenced by inefficient thermal management, by the heat generated in the sample, or by rod-climbing due to the Weissenberg effect. We investigate the effect of these phenomena with simulations in COMSOL Multiphysics®. Our model is based on the axial symmetric (2D) formulation of the two-phase flow with the ...
