The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship [1]. One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers [2]. They developed from a desire for ‘fresh’ tea and the first ship to return with the new season’s tea could charge a higher ...

Wind Flow Modeling of Area Surrounding the Case Western Reserve University Wind Turbine

M. Fernandes[1], D. Matthiesen[1]
[1]Case Western Reserve University, Cleveland, OH, USA

The CWRU Turbine is a research turbine located in a urban campus in Cleveland, Ohio. This location may create turbulence, resulting in a possible loss in energy generation. This research attempts to answers the question of whether the wind flow is affected by the buildings or not. The surrounding buildings, which vary in height from 20 to 40 meters, may affect the wind patterns at the hub ...

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 concentration evolution and cellular growth, as well as efficient heat transfer, allows the production of high ...

3D Modelling of Flow Dynamics in Packed Beds of Low Aspect Ratio - new

F. Alzahrani[1], F. Aiouache[1]
[1]Engineering Department, Lancaster University, Lancaster, UK

This work used the 3D CFD modeling to investigate non-uniform deactivation in packed bed reactors of low aspect ratios under steady state and dynamic operations. In order to explore the effects of condition of instability on local deactivation, detailed knowledge of flow dynamics (i.e. local structure of the packed bed, pressure drops and interstitial flow in the void space), heat and mass rate ...

Computational Fluid Dynamics Approach to Evaluate Electrostatic Precipitator Performance

M. Ahmadi [1]
[1] Faculty of Engineering Technology, University of Twente, Enschede, The Netherlands

Electrostatic precipitation is an extremely efficient way of filtering fine particles from the airstream. Electrostatic precipitators (ESPs) can control airborne emission without significantly slowing down the rate of flow, because of the low pressure drop across this type of filters. A computational model was developed for the simulation of ESP operation and the parameters of interest were ...

Multiphysics Modelling in the Electromagnetic Levitation and Melting of Liquid Metals

A. A. Roy, V. Bojarevics, and K. Pericleous
University of Greenwich
London, UK

The aim of this article is to demonstrate the capability of the software for predicting free-surface motion and internal fluid flow in an electromagnetically levitated sample of liquid metal. Multiphysics solutions which demonstrate the usefulness of Comsol as a powerful MHD simulation tool have been generated to two industrial problems using the ALE moving-mesh module in combination with the ...

Fluid-Thermal Analysis of an Inverter with Air Cooling

R. V. Arimilli[1], A. H. Nejad[1], K. Ekici[1]
[1]The University of Tennessee, Knoxville, TN, USA

A new simple air-cooled inverter design is numerically investigated using COMSOL Multiphysics® software. The thermal-fluid analysis is based on a three-dimensional conjugate heat transfer model in which the flow field is assumed to be laminar. A rigorous mesh convergence was performed to ensure that the overall energy balance error is within engineering accuracy while the computational cost is ...

[1]St. Mary's Group of Institutions, Jawaharlal Nehru Technological University, Hyderabad, Telangana, India

Fluid and structure Interaction analysis can be applied to versatile fields of engineering applications, helps in understanding the affects of one material on other, thereby reducing the effect of physical parameters like nonlinear response, vibration in flow channel etc. Rapid development of technology led to the application of this Fluid-Structure Interaction (FSI) in Microfluidics based ...

A Model of Heat Transfer in Metal Foaming

Metal foams are interesting materials with many potential applications. Foamed metals or alloys include gas voids in the material structure and therefore the density is introduced as a new variable, with the real possibility to modify ad hoc their physical properties. In the indirect foaming process carried out in a furnace, simultaneous mass, momentum and energy transfer between three phases, ...

Hydrodynamic and Thermal Modeling in a Deep Geothermal Aquifer, Faulted Sedimentary Basin, France

E. Malcuit[1], A.L. Gille[1]
[1]CFG Services, Orléans, France

Within projects of geothermal energy, we need hydrodynamic and thermal modeling to forecast the impacts of geothermal deep wells on existing wells. In case of pumping and reinjection of the geothermal fluid in a deep groundwater reservoir, located in a sedimentary basin with lateral and vertical lithology variations and major faults, it is fundamental to understand the behaviour of the ...
