EXPERIMENTAL STUDIES, GEOMETRY ACQUISITION AND GRID GENERATION OF DIESEL ENGINE INLET PORT FOR THREE DIMENSIONAL CALIBRATED CFD CODE FOR FUTURISTIC DESIGN

A typical diesel engine port is of complicated geometry . This paper addresses the experimental studies of intake port of a four cylinder diesel engine for different vacuum pressures and valve lift positions. In this study the cylinder head is experimented through a paddle wheel flow setup which gives the flow coefficient and swirl number as output. The main scope of the work is to understand the flow behaviour through the intake port and finally to determine mean flow coefficient and mean swirl number for different valve lift ratios L/D, where L is valve lift and D is bore diameter. This paper also addresses the geometry acquisition and grid generation for three dimensional Computational Fluid Analysis for flow filed computation and obtain a calibrated CFD code for future design once the code is validated with experimental result
