Experimental measurements of gravity casting flow

Numerical simulation of in-cylinder tumble flow field measurements and comparison to experimental results

This paper presents a comparison between measured and predicted results of the in-cylinder tumble flow and the flow coefficient generated by a port-valve-liner assembly on a steady-flow test bench. In this study, computational fluid dynamics (CFD) methods were employed to gain further insight into characteristics of an engine. The purpose was to advance understanding of the stationary turbulenc...

Geometric and computational aspects of gravity casting

In the manufacturing industry, nding an orientation for a mold that eliminates surface defects and insures a complete ll after the termination of the gravity casting process is an important and diicult problem which has not previously been investigated formally. We initiate the study of the gravity casting process from a geometric perspective and present an optimal (n log n) time algorithm that...

Turbulent flow structure in experimental laboratory wind-generated gravity waves

Experimental benchmark for casting problems

The problem motivating the current work is a mould filling during casting process. The aim of our analysis is to provide a simple experimental model simulating the main flow characteristics accompanying such process. Hence, the hot fluid is supplied under high pressure into an inclined box. Fluid flows inside the box between two cold isothermal walls, passing obstacles simulating internal compl...

Transient Fluid Flow during Steady Continuous Casting of Steel Slabs: Part I. Measurements and Modeling of Two-phase Flow

Unstable mold flow could induce surface velocity and level fluctuations, and entrain slag, leading to surface defects during continuous casting of steel. Both argon gas injection and ElectroMagnetic Braking (EMBr) greatly affect transient mold flow and stability. Part I of this two-part article investigates transient flow of steel and argon in the nozzle and mold during nominally steady-state c...
