Research on Aerodynamic Drag Reduction by Vortex Generators




Introduction

To save energy and to protect the global environment,
fuel consumption reduction is primary concern of
automotive development. In vehicle body development,
reduction of drag is essential for improving fuel
consumption and driving performance, and if an aerodynamically
refined body is also aesthetically attractive,
it will contribute much to increase the vehicle’s appeal
to p ....etc

EFFECT OF DIMENSIONAL PARAMETERS ON THE PERFORMANCE OF VORTEX TUBE


INTRODUCTION

Vortex tube is a simple device, which can cause energy separation. The principle of vortex tube is vortices produced by tangential velocity as a main driving force for the energy separation in the vortex tube.
It consists of nozzle, vortex chamber, separating cold plate, hot valve, and hot and cold end without any moving parts. In the vortex tube, when works, the compressed air expands in the nozzle ....etc

Compound Vortex Controlled Combustion
CVCC is a trademark by the Honda Motor Company for a device used to reduce automotive emissions called Compound Vortex Controlled Combustion. This technology allowed Honda's cars to meet the 1970s US Emission requirements without a catalytic converter, and first appeared on the 1975 ED1 engine. It is a form of stratified charge engine.

Honda CVCC engines have normal inlet and exhaust valves, plus a small auxiliary inlet valve which provides a relatively rich a ....etc

ABSTRACT

Vortex refrigeration is a highly sophisticated system that contains a vortex tube which due to centrifugal force expels the internal energy of the air while the air at the centre core is made cooler. In this type of system the effectiveness is too low but considering its small size this can’t be ruled off. This is used as personal cooling system in suits that are designed to withstand heat.

ABSTRACT
VORTEX GENERATORS
This topic provides basic working principle of a vortex generator suitable for automobiles. Vortex generator has a vital role in increasing the fuel economy and aerodynamic stability. This enables them reduce the drag force acting on it.
There are several methods for positioning the vortex generators over the vehicles. The key results of a simple experiment conducted on Toyota prius exemplifying the advantages of vortex generators discussed here.
