Design optimisation of air filters using ANSYS fluent

Design Optimization of Actuators Using ANSYS

Research and development on actuators has been accelerated with the aid of virtual prototyping software, like ANSYS. This is illustrated with two successful cases using ANSYS to design and optimize micro-electromechanical actuators. The first case is topology optimization of head suspension assembly for hard disk drive. The second case is design optimization of polymeric thermal micro-actuator....

CFD study of Jet Impingement Test erosion using Ansys Fluent® and OpenFOAM®

The initial aim of this study was to compare OpenFoam and Ansys Fluent in order to verify OpenFoam’s Lagrangian Library and erosion capabilities. However, it was found that previous versions of Fluent have been providing wrong results for the discrete phase and the differences with the latest version (Ansys Fluent 15) are shown. A Submerged Jet Impingement Test is an effective method for studyi...

Optimisation of Spatial Joins Using Filters

1 I n t r o d u c t i o n In the past, a lot of research has been done on query optimization techniques for (relational) databases. A survey is given in [10]. Optimization efforts mainly concentrated on queries s temming from administrative applications. Recently, databases are increasingly used not only for administrative, but also for technical applications. Technical applications, e.g. CAD/C...

Modeling particle-loaded single fiber efficiency and fiber drag using ANSYS–Fluent CFD code

In this paper, we present a methodology for simulating pressure drop and collection efficiency of a filter medium during instantaneous particle loading using the ANSYS–Fluent CFD code, enhanced with inhouse subroutines. The simulations are comprised of a numerical solution of the Stokes equations for obtaining the air flow field, and Lagrangian particle tracking, for determining the particle co...
