Computational fluid dynamics (CFD) is a simulation tool, which uses powerful computer and applied mathematics to model fluid flow situations for the prediction of heat, mass and momentum transfer and optimal design in industrial processes. It is only in recent years that CFD has been applied in the food processing industry. This paper reviews the application of CFD in food processing industries...

Numerical predictive accuracy is investigated for transient component heat transfer using a Computational Fluid Dynamics (CFD) code dedicated to the thermal analysis of electronic equipment. The test cases are based on a single Printed Circuit Board (PCB)-mounted, 160-lead PQFP component, analyzed in still-air, and both 1 and 2.25 m/s forced airflows. Three types of transient operating conditio...

This work initially focuses on developing a computational fluid dynamics (CFD) model of an industrialscale steam methane reforming reactor (reforming tube) used to produce hydrogen. Subsequently, we design and evaluate three different feedback control schemes to drive the area-weighted average hydrogen mole fraction measured at the reforming tube outlet ( x̄H outlet 2 ) to a desired set-point va...

Many chemical reactions are carried out using stirred tanks, and the efficiency of such systems depends on the quality of mixing, which has been a subject of research for many years. For solid–liquid mixing, traditionally the research efforts were geared towards determining mixing features such as off-bottom solid suspension using experimental techniques. In a few studies that focused on the de...

Computational fluid dynamics (CFD) has become an attractive tool in understanding the characteristic of air flow in the human lungs. Due to inter-subject variations, subject-specific simulations are essential for understanding structurefunction relationship, assessing lung function and improving drug delivery. However, currently the subject-specific CFD analysis remains challenging due, in larg...

Virtual reality techniques particularly in the field of CFD (computational fluid dynamics) are of growing importance due to their ability to offer comfortable means to interactively explore 3D data sets. The growing accuracy of the simulations brings modern main memory based visualization frameworks to their limits, inducing a limitation on CFD data sizes and an increase in query response times...

Obtaining reliable CFD predictions of the bronchial flow that reflects the actual flow within a living lung requires the development of a deforming airways model, and the imposition of physiological subject-specific boundary conditions. This thesis addresses these two issues by the development of dynamic CFD models of the bronchial airways using a dynamic CT data set covering the breathing cycl...

For a long period of time, design and manufacturing technology of high flow rated vertically suspended pumps (VSPs) which have an extensive applications in many industries such as water and wastewater, mining, petrochemical and oil and gas industries, used to be imported from European countries. For the first time in Iran's pump industry, with the support of Ministry of Petrochemical[ah1]  and ...

Despite the many advantages, ejector refrigeration systems have not been able to penetrate market because of two prevailing reasons: low coefficient performance and relevant influence operation on whole system. Indeed, depends local flow phenomena occurring within ejector. Thus, improving relies understanding fluid dynamic at "component-scale" integrating such information "system-scale". This p...
