Gradient-based aerodynamic shape optimization, based on Computational Fluid Dynamics analysis of the flow, is a method that can automatically improve designs of aircraft components. The prospect is to reduce a cost function that reflects aerodynamic performances.When the shape is described by a large number of parameters, the calculation of one gradient of the cost function [...]
CFD-analysis of hydrodynamic lubrication of textured surfaces
There are countless numbers of lubricated components everywhere in life and an improvement in efficiency would lead to great cost efficiency improvements in many applications. This makes it an area which is subject to a great deal of research. Here, an approach to increase the efficiency in hydrodynamic lubrication is made where the influences from [...]
Aerosol Impactor – Aerosol Sampling
The collection and characterization of chemical and biological aerosols is vital to several aspects of particle research for example toxicological studies, pollutant sampling, and biohazard analysis. This study presents the simulation of a low cutpoint, high volume aerosol sampling gadget referred to as virtual impactor
CFD Simulations of Pressure Loss in Pipes with Different Geometries
The passive security systems protect the passengers when the car has an important accident. These systems are based in a good and strength car structure to not deform the passenger cabin. In Gestamp Hardtech are producing pieces with an important strength without increasing the car weight. These pieces are produced using the hot stamping process [...]
