Solid-Liquid Phase Change Simulation Applied to a Cylindrical Latent Heat Energy Storage System
One way of storing thermal energy is through the use of latent heat energy storage systems. One such system, composed of a cylindrical container filled with paraffin wax, through which a copper pipe carrying hot water is inserted, is presented in this paper. It is shown that the physical ... Per saperne di più
Wall Effects in Convective Heat Transfer from a Sphere to Power Law Fluids in Tubes
Heat transfer from a sphere having a uniform temperature and falling axially in a cylindrical tube filled with an incompressible power-law liquid is numerically investigated. The governing equations for simultaneous flow around a confined sphere and heat transfer to power-law fluids were ... Per saperne di più
Multiphysics Simulation of a Packed Bed Reactor
Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large ... Per saperne di più
The Use of CFD Simulations in Learning Fluid Mechanics at the Undergraduate Level
Simple, accurate CFD simulations using COMSOL Multiphysics are used in a senior-level undergraduate course as a means to explore a number of fluid flows with the intent of developing a deep understanding of the underlying fluid mechanical mechanisms involved in the flows. Students also ... Per saperne di più
Deep Desulfurization of Diesel Using a Single-Phase Micro-Reactor
This paper describes the benefits of computational fluid dynamics in the development of a microreactor used in the desulfurization of aromatic compounds. It is crucial to verify diffusion and extinction coefficients to ensure accurate simulation results prior to experiments. COMSOL ... Per saperne di più
Error Analysis in Estimating Temperature-Dependent Thermal Diffusivity and Kinetic Parameters using Heat Penetration Data
Growing consumer demand for nutraceuticals has stimulated interest by food companies to increase levels of these health-promoting compounds. Thermal processing of canned foods in a retort produces a unique problem: some of the nutraceuticals are highly sensitive to temperature, and ... Per saperne di più
Model of a Filament Assisted CVD Reactor
In this presentation we are dealing with the computational fluid model of a Filament Assisted Chemical Vapor Deposition (FACVD) reactor. Proposed strategy in this study involved several steps: (a) development a computational model for FACVD process capable to describe and obtain with ... Per saperne di più
Linear Convection and Conduction in Cylinders of Water Exposed to Periodic Thermal Stimuli
Primary reference standards for determining absorbed dose to water in radiotherapy beams used at cancer clinics and hospitals ultimately must make reference to the temperature change in water produced by ionizing radiation. The most direct experimental technique for this purpose is water ... Per saperne di più
Coupled Heat and Mass Transfer Processes in Enclosed Environments
Geothermally driven natural convection in enclosures is a ubiquitous process occurring in many physical environments such as caves, mines, etc. We have numerically simulated laminar and turbulent natural convection in isolated air-filled cavities, buried in a more conductive rock mass. ...
