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.

Discussion: As shown in the result section‚ the drag force increases steadily with increasing wind speed. However‚ for high wind speeds with largest sphere‚ this is not true. There is a region that the sphere experiences a large drop of drag force. The drag coefficient remains relatively constant for most cases. However‚ when a Reynolds number reach about 300‚000‚ and the sphere is the largest one; for this case‚ the drag coefficient drops abruptly. We also found that for the same wind speed‚ the

Consider a steady two-dimensional flow of Maxwell‚ Jeffrey and Oldroyd-B nanofluids over a cone having radius and half-angle . x-axis varies along the surface of cone and y-axis is perpendicular to it. The temperature and concentration distributions are vary along the surface of the cone. A variable magnetic field is applied along -direction as shown in Fig.1. A variable temperature along with the thermophoresis and Brownian motion effects are taken into account. and are the ambient temperature

The breaking of water stream under the light of total internal reflection of laser Jiho Yang Colegio Retamar Abstract In this paper‚ we report the circumstances that produce breaking of water stream. The usual way to visualize this is by using a strobe‚ as how they do in Science museums. Experimental methodology that we have used to investigate this topic is based on an experiment carried out by two scientists in 1850 that contributed to studies about total reflections. By using a laser

CEE 320 Fluid Mechanics Lab Head Loss Through a Valve April 24‚ 2012 Abstract This experiment determined the relationship between the head loss through a gate valve and the degree of opening of that valve with varying flow rates. The objective of this experiment was to determine the valve loss coefficient‚ K‚ for a specific gate valve as a function of both the pipe Reynolds Number‚ and the degree of opening. The relationship between the Reynolds Number and the friction factor was

5.2 Principle of Operation of N-Channel JFET: These are two prerequisites while considering the principle of operation of JFET. Gates are always reverse biased and therefore Gate current IG is practically zero. Source and Drain terminal should be joined together through a voltage source called VDS‚ drain to source voltage. In an N-channel JFET‚ source terminal is connected to the negative end of the drain to source supply voltage to send the lectron from source to drain and similarly for an P-channel

DESIGN OF AN ABSORBER Problem statement To design an absorber (packed tower) for the absorption of 785.15 kg/h of sodium metabisulphite (Na2S2O5) at an average temperature of 68˚C and Y atm pressure with sulphur dioxide gas counter-currently reacting with Na2SO3 rich feed. Introduction Absorbers are vertical towers used in distillation‚ gas absorption and liquid-liquid extraction processes. Absorbers can be operated co-currently or counter currently. In the former‚ both fluids involved are fed
