Sensitivity Analysis of CPP’s for Solvent Removal Process of a API-Protein Bonded Nano-Suspension
Solvent extraction and evaporation is a widely used unit operation in the manufacturing of micro and nano-particles. Due to the weak bond of the API to the protein, the product is highly sensitive to temperature, mechanical mixing and extraction/evaporation rate. A slow extraction ... 詳細を見る
Iron Ore Sintering Process Model to Study Local Permeability Control
The iron ore sintering process prepares fine iron ore for the blast furnace process. A mixture consisting of iron ore, coke (fuel) and additives is ignited at the top and air is sucked from below to move a combustion front down through the bed. Most of the sintering plants use ... 詳細を見る
3D Unsteady CFD with Heat and Mass Transfer Simulations of Solar Adsorption Cooling System for Buildings
In recent years, extensive attention has been paid on the application of solar cooling for buildings. Amongst cooling technologies, low-temperature solar-driven adsorption cooling systems are emerging viable alternatives to electricity-driven vapour compression systems. They seem to have ... 詳細を見る
Electrochemical Machining with Nonsymmetric Suction of Electrolyte Flow
In electrochemical machining process, it is very important to control electrolyte flow field to remove contamination such as slug, or gas to be generated by the machining process as well as heat control for electrolyte, machining tool and work piece. To reduce the overcut of workpiece, ... 詳細を見る
Simulation of Molecular Transport of an Electroporated Cell using COMSOL Multiphysics®
Electroporation is a highly efficient cellular transfection method which is used to inject molecules into living cells. The electroporation involves creating temporary pores in cell membranes using an electrical field. It has been successfully utilized in medicine and biology for ... 詳細を見る
Virtual Design of a Four-Bed Molecular Sieve for Exploration
Aboard the International Space Station, carbon dioxide is removed from the atmosphere using a four-bed adsorptive separation process, referred to generally as a 4-Bed Molecular Sieve (4BMS). Experience with the current 4BMS design in space has led to a list of areas for improvement for a ... 詳細を見る
A Single Platform Approach for Kinetics Identification, Reaction Engineering, and Model Deployment
Chemical reaction kinetics identification is an essential and enabling step for reaction engineering designs. This presentation explores the COMSOL platform for performing the kinetics estimation and subsequent reaction engineering of a catalytic reaction with formation of competing ... 詳細を見る
Mapping the Limitations of Breakthrough Analysis in Fixed-Bed Adsorption
In a recent publication (Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption, Ind. Eng. Chem. Res. 2016, 55, 4734-4748) the authors discussed the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer ... 詳細を見る
Electrical and Bubbly Flow Modeling of a Molten Salt Electrolysis Cell
A laboratory-scale electrolysis cell for the recovery of metals is simulated with COMSOL Multiphysics® software. Two models are implemented: an electrical model simulating the current density (reaction rate) distribution at the electrodes and a laminar bubbly flow model which solves for ... 詳細を見る
Transient CFD Investigation of a Photocatalytic Multi-tube Reactor
As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a ... 詳細を見る
