Flow visualization of three dimensional coherent motions in turbulent meandering flow.

Optical digital sensor for three-dimensional turbulent flow visualization

The Nikon Coolpix885® conventional digital camera is utilized to reform three-dimensional (3-D) turbulent pattern on lake that is situated in University Technology Malaysia (UTM). The main objective of this study is to use fuzzy arithmetic to reduce the errors arising from noise in digital camera data when constructing turbulent pattern flow. In doing so, the fuzzy B-spline algorithm, which ass...

THREE DIMENSIONAL MODELING OF TURBULENT FLOW WITH FREE SURFACE IN MOLD FILLING

In the present study a Finite Difference Method has been developed to model the transient incompressible turbulent free surface fluid flow. A single fluid has been selected for modeling of mold filling and The SOLA VOF 3D technique was modified to increase the accuracy of simulation of filling phenomena for shape castings. For modeling the turbulence phenomena k-e standard model was used. In or...

Heat Transfer in Three-Dimensional Flow along a Porous Plate

An analysis of heat transfer in the flow of a viscous, in-compressible fluid along an infinite porous plate is presented when the plate is subjected to a transverse sinusoidal suction. The flow field becomes three-dimensional due to this type of suction velocity. Expressions for the flow and temperature fields are obtained by series expansion method. It is found during the course of discussion ...
