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...
متن کاملShape Optimization for Inverse Electromagnetic Casting Problems
In this paper we present an algorithm for inverse optimization problems concerning electromagnetic casting of molten metals. We are interested in locating suitable inductors around the molten metal so that the equilibrium shape be as near as possible to a desired target shape. A Simultaneous Analysis and Design (SAND) mathematical programming formulation is stated for the inverse problem. The r...
متن کاملAluminum and Aluminum Alloys Casting Problems
Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...
متن کاملSelected laboratory benchmarks for validating numerical simulation of casting problems
The complicated physical phenomena which occur within solidifying metals during casting processes can not be easily observed. In the present paper the results of laboratory experiments with mould filling and freezing are presented. The experimental benchmarks have been constructed, based on so called analog fluids which are transparent and have well known physical properties: succinonitrile, po...
متن کاملDesign for Casting - A New Paradigm for Preventing Potential Problems
Design revisions are expensive and time consuming. Yet, these are inevitable because product designers have limited knowledge about casting processes and have no means to evaluate the influence of design features on castability (costs, quality and productivity). Problems appear much later, at the tooling or manufacturing stage, when it is much more expensive to incorporate changes than at the d...
