Simulation and Parametric Study of a PDMS Based Valveless Micropump Using FSI Approach
In this paper simulation and parametric study of a PDMS valveless micropump using Fluid-Structure Interaction (FSI) appraoch is presented. The simulation for the valveless micropump were carried out in COMSOL Multiphysics software. In case of a valveless micropump diffuser/nozzle element ... Read More
Simulation of Supercritical Fluid Extraction Process
This paper deals with the simulation of mathematical model for supercritical extraction. Reverchon, 1996 extracted sage oil using supercritical extraction method from sage leaves at 9 MPa and 50 ᵒC. Four mean size of sage leaves ranging from 0.25 to 3.10 mm were taken for extraction with ... Read More
Friction Factor for Perforated Pipes
Perforated pipes are extensively used to control exhaust noise in automobiles [1-4]. The energy loss associated with the perforations leads to back pressure which needs to be quantified and minimized [5]. An objective approach presented in [6] is the introduction of friction factor for ... Read More
Numerical Simulation of Auto-Propulsion Mechanism of Microorganism Inside a Microchannel
The present study manifests the several ground breaking flow phenomena arising out of hydrodynamic interactions between two microorganisms swimming inside a microchannel with close proximity. The results theorized in the present investigation scrutinizes the varying behavior of the ... Read More
Fluid Flow Modeling in a Bioreactor Applied to Wine Production
Wine quality is strongly dependent on the operation parameters of the production process. In batch or fed batch reactors, the rotating velocity should be carefully controlled to avoid cellular stress and ensure adequate mixing of the mixture. Moreover, precise control of substrates ... Read More
CAE-Based Design and Optimization of a Plasma Reactor for Hydrocarbon Processing
Plasma reactors can be applied to the conversion of waste, biomass and fuels to synthesis gas (mixture of hydrogen and carbon dioxide) with efficiencies as higher as 90-95% and low energy demand, depending on the design optimization. In this work, a multi-step approach was applied to the ... Read More
Simulation of Flow in a Rectangular Channel of a PEM Fuel Cell
The performance of a PEMFC depends on several factors, including the flow inside gas channels. Low gas velocity inside the channel can make water management more difficult, possibly causing water to accumulate and condense in certain regions of the cell. In the present work, COMSOL ... Read More
Mathematical Formulation of a PEM Fuel Cell Model
The idea of a friendly implementation of a mathematical formulation using specialist software was performed with the support of COMSOL Multiphysics® software with Chemical Reaction Engineering and Batteries & Fuel Cell Modules. The real problem of a Proton Exchange Membrane – PEM ... Read More
