The solidification for lost foam castings

During the period of the previous computational modeling research and current of filling and solidification for Lost Foam castings maturation. The improvements described in this section and later in Subtask 4.1 technology is necessary for this maturity. A major software company cost through commercial, Flow Science (Flow3D), ESI North America and Magma Soft sponsors share for this. The three companies showed strong interests in improving the use of experimental data developed at UAB codes. Flow3D historically expressed the most interest with assistance in processing issues to resolve and willingness to incorporate changes to their code.

General Motors also developed their own code, “Fill Foam”, the lost foam process. This code has developed the best use of research achievements made by UAB. The code was submitted to the commercial software companies; however, had none of the companies willing to spend the necessary funds to integrate the code into theirs because of the lack of return on investment. General Motors the code is widely used to identify issues casting blame on existing projections and production parameters for identifying new projections. Processed A trial simulation using the software matrix Procast ESI. Input parameters such as pattern properties, coating thickness, coating permeability, gas fraction, and heat transfer coefficients from the databases selected ESI and UAB. Data from these two sources of different values. From the simulation results predict that the velocity was filled metal using half the data UAB data using ESI.

Agrees filled using metal velocity UAB data with data measured using real-time X-Ray. Effects of permeability was coating on metal but at higher velocity than measuring permeability value. The effect was not as pronounced as observed in Real Time X-Ray. Effects were predictions of a metal filling glue section. The response generated by simply metal metal fill stop for one second when the metal reached the glue joint. Based on these results it was decided not to use the ESI software for additional simulations for the program effective.
