Topology Optimization in Multiphysics Problems
This presentation deals with a density based topology optimization for multiphysics problems implemented in COMSOL Multiphysics. Using this method, we are going to design a heat exchanger for maximizing the performance under a constant input power. En savoir plus
Modeling Charge/Discharge Heat Generation of Li-ion Cells and Experimental Verification of Temperature Distribution
Modeling the heat generation and the heat transfer of the electrode of lithium-ion battery are introduced. There are several models, such as an homogeneous heating model and a model considering the current and reaction distribution of electrode. Generally, electrodes have large area and ... En savoir plus
Optimal Design of Flow Distributors for Detecting Blocked Microreactors
When the production capacity of micro chemical plants is increased by numbering-up approach, it is important to realize the uniform flow distribution among the parallelized microreactors. In addition, a blocked microreactor needs to be identified as early as possible to achieve the ... En savoir plus
Analysis on Reaction Mechanism and Kinetics of CVD using COMSOL Multiphysics®
Chemical vapor deposition (CVD) is widely used in various fields including the fabrication of electronic devices due to its uniform film formation capability on the large-scale wafers and the minute 3D structures. In CVD, precursors (metal compounds) are commonly reacted in gas-phase as ... En savoir plus
Quantitative Analysis Design of MEMS Based Micropreconcentrator for Cancer Diagnosis
