Abstract
In this study, calendering process of an Oldroyd 4-constant model with the non-linear slip condition is presented. The fundamental laws are used to formulate the flow equations and then are simplified under lubrication approximation theory. We introduced the stream function to eradicate the pressure gradient and then numerically solved the final equations using the "bvp4c method" to determine the stream function and velocity profiles. The pressure gradient, pressure, and mechanical quantities of calendering operations are computed using the Runge-Kutta 4 th -order approach. Using a variety of graphs, it is discussed how the slip, Hartmann number, and material parameters of an Oldroyd 4-constant fluid affect the velocity, pressure gradient, and other associated characteristics of calendering. The results reveal that on comparing to the no-slip situation, the pressure distribution inside the calender and the length of contact decreases with increasing slip parameter values. On the other hand, the Hartmann number is responsible to enhance pressure. Furthermore, a reduction is observed in final sheet thickness with increases the values of the slip parameter ( Kn ). The force and power are the decreasing function of 1 , conversely, these quantities increase with enhancing the values of leave off distance ( ).
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
