The University of Queensland‚ CRCMining‚ Brisbane‚ Australia K. Hooman The University of Queensland‚ Brisbane‚ Australia ABSTRACT: In recent years‚ Computational Fluid Dynamics‚ CFD‚ has been commonly utilized in the mining industry to model the fluid flow behavior in underground mine workings. This paper uses CFD modeling to simulate the airflow behavior in underground crosscut regions‚ where brattice sails are used to direct the airflow into these regions. Brattice sails are cost effective

CFD PROJECT REPORT Submitted by Sai Yashwanth M IMPACT OF AERODYNAMICS ON AUTOMOBILES INTRODUCTION Aerodynamic forces are caused by the relative motion of automobiles with air and they cause: Drag (resistance to forward motion) Lift / down force (come into play during cornering and acceleration) Lateral forces (comes into play during cornering) Moments in roll‚ pitch and yaw As a result these factors have to be taken into consideration during automobile design.

Premium Drag Viscosity Aerodynamics
How do sharks reduce drag? And what are the engineering applications? There are three types of drag present on the shark during locomotion. The first type of drag is known as frictional drag‚ which is the greatest element of drags in the shark. This is arises due to the friction created between the skin and the boundary layer and can be reduced with a condition that the boundary layer maintains a turbulent flow. The second type of drag is pressure drag‚ which causes by water deflecting off the moving

This is to gain high accuracy during topology optimisation and to match the same accuracy of the pressure gained from the surface used in the CFD simulation. The surface mesh was then used to generate a matching three-dimensional (3-D) finite volume tetra-element mesh for the internal structure (design space) of the wings. The fuselage was meshed using a moderate size 3-D volume tetra-element
