Book Numerical Simulation of Directional Solidification of Castings

Download or read book Numerical Simulation of Directional Solidification of Castings written by Y. Quiping and published by . This book was released on 1985 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some rules for numerical simulation of the directional solidification process with steep temperature gradient were investigated. In order to improve the accuracy of calculation, the effect of the term (del k/del T) (del T/del Z) squared in the heat transfer equation on the outcome with steep temperature gradient is discussed. Problems such as how to treat latent heat of solidification, thermal properties at the casting/mold interface and the initial condition are also analyzed. Both finite difference and finite element methods were used to calculate the same casting under identical initial and boundary conditions with the same physical parameters. The results were compared.

Book Foundry Processes

Download or read book Foundry Processes written by Seymour Katz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a number of years it has been a General Motors Research Laboratories custom to hold a symposium on a subject which is new and emerging, and to invite the best people in the world in that subject to come together to talk to each other. Initially, I had some difficulty in regarding foundry processes as a new and emerging subject. Copper alloys have been in foundry practice for about six thousand years. Foundrymen working with those alloys have been recognized, as such, for nearly all that time. Iron has a much shorter history, probably only three or four thousand years. So what's new? What is new is that a subject which has always been so complex and so difficult that it could only be a craft skill, with bits and pieces of knowledge and bits and pieces of insight, has begun to yield to new abilities to solve very complex problems. We do this now because we can handle great amounts of data by computational means, using new and more complicated theoretical treatments than we could deal with before. In fact, we have a new technology with which we can attack these terribly difficult problems. Thus, foundry processing is becoming a new subject because new things can be done with it.

Book Science and Engineering of Casting Solidification Second Edition

Download or read book Science and Engineering of Casting Solidification Second Edition written by Doru Michael Stefanescu and published by Springer Science & Business Media. This book was released on 2008-12-03 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stefanescu here attempts to describe solidification theory through the complex mathematical apparatus required for a fundamental treatment of the problem. The mathematics is however restricted to the elements essential to attain a working knowledge in the field. This is in line with the main goal of the book, which is to educate the reader in the fast moving area of computational modeling of solidification of castings. A special effort has been made to introduce the reader to the latest developments in solidification theory including, in this second edition, a new chapter on semi-solid casting.

Book Modeling of Shrinkage Porosity Defect Formation During Alloy Solidification

Download or read book Modeling of Shrinkage Porosity Defect Formation During Alloy Solidification written by Vahid Khalajzadeh and published by . This book was released on 2018 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The model, called "advanced feeding model", includes 3D multi-phase continuity, momentum and pore growth rate equations which inputs the material properties and transient temperature fields, and outputs the feeding velocity, liquid pressure and porosity distributions in castings. To solve the model equations, a computational code with a finite-volume approach is developed for the flow calculations. To validate the model, predicted results are compared with the experimental data. The comparison results show that the advanced feeding model can accurately predict the occurrence of shrinkage porosity defects in metal castings. Finally, the model is optimized by performing several parametric studies on the model variables.
