Flow Calorimetry Modeling With Heat Transfer Module new
We used COMSOL Multiphysics® simulation software to model mass flow calorimetry in a metal-hydride chemisorption reaction. Using a reaction chamber with 100W input, we measured the temperature of flowing water in contact with the chamber and calculated the heat output of our reaction. ... Saiba Mais
Application of an Electromagnetic Analogy in the Simulation of a Problem in Classical Hydrodynamics new
The present author’s specialty is Aerodynamics, a field in which problems in unbounded fluid domains are common. The COMSOL Multiphysics® simulation software's support of Infinite Elements is attractive as a tool for addressing such problems. Be that as it may, neither the COMSOL ... Saiba Mais
Keratin Biomaterial Diffusivity Determination in a 1D-Like Channel using COMSOL Multiphysics® and MATLAB® new
Introduction: Keratin protein biomaterials (KTN) are used in various tissue engineering applications including liquid infusions and gel implants. Random movement of molecular species is characterized by Fick’s laws of diffusion (and velocity-dependent convection) with the ... Saiba Mais
An Overpressure Furnace: Understanding Performance and Analysis-Led Design Improvements new
Bi2Sr2CaCu2O8+δ (Bi 2212) is being developed as a high temperature superconductor (HTS) technology with practical use in ultra-high field (+30 T) magnets. A critical processing step for this conductor is a ~890 degC heat treatment at elevated pressure (~50 atm). The reaction of this ... Saiba Mais
Estimating Parasitic Capacitances in MEMS Microphones using Finite Element Modeling new
MEMS microphones consist of a conductive backplate and a conductive flexible membrane. The backplate and the membrane are at a certain distance from each other to be interpreted as parallel plates of a capacitor. When a bias voltage is applied to the electrodes, membrane deflection ... Saiba Mais
Three-Dimensional Mixed Convection in a Rectangular Duct new
Numerical study of fluid flow and heat transfer in a finite three-dimensional rectangular, horizontal duct of length to width, and length to height ratio of 12:1 is investigated in this study. The left wall of the duct is uniformly heated while the right, top, and bottom walls are ... Saiba Mais
Multiphysics Multi-Material Topology Optimization of a Thermal Actuator with COMSOL Multiphysics® Simulation Software new
Introduction: Design of a thermally driven actuator used in Micro Electro Mechanical Systems (MEMS) with two different metal materials is discussed. To achieve best performance of the thermally driven actuator in this work, it is desired to use a metal material with both high coefficient ... Saiba Mais
Finite-Element Analysis of Unsteady Flow Past a Circular Cylinder Based on a Variational Multiscale Method new
Incompressible flow field past a circular cylinder within parallel plate channel is very important in industry and science. As well known, beyond the Reynolds number based on the diameter of the cylinder and uniform flow velocity of 40, flow past a circular cylinder cannot hold its two ... Saiba Mais
2D Flow Past a Confined Circular Cylinder with Sinusoidal Ridges new
Flow past a circular cylinder arises in many engineering applications, but there is significantly less work studying flow past a cylinder in a confined domain, such as pipe flow or flow in a plane channel. There are many applications where the scaling of a particular problem requires ... Saiba Mais
Actuation Force Study of Next Generation Micro Shutter Array for More Reliable Actuation new
Micro shutter array (MSA) is a programmable optical spatial filtering device fabricated by micro electro-mechanical system (MEMS) technology. It was originally developed for James Webb Space Telescope (JWST) to enable multi-object spectroscopy and operated by a moving magnet. Next ... Saiba Mais
