| Abstract | This paper analyzes the steady, laminar, two-dimensional flow and heat transfer of a second-grade viscoelastic fluid over a flat plate subjected to continuous stretching. Injection and suction effects are also investigated. The mathematical model of the problem was derived from the constitutive tensor for an incompressible fluid of the second grade, followed by thermodynamic considerations and usual boundary layer assumptions. The generalized integral transform technique (GITT) was used to transform the governing partial differential equations (continuity, conservation of momentum and energy) within the boundary layer hypotheses on a coupled system of ordinary differential equations. The numerical solution of the system of equations was performed using the appropriate subroutine DIVPAG from the IMSL Library, which it is well-indicated for solving initial value problems with stiff characteristics. Convergence behaviors of the numerical results for the velocity and temperature fields were discussed as functions of parameters of interest. Investigations on the influence of viscoelastic parameter (K), injection or suction parameter (F) and Prandtl number (Pr) were performed in order to evaluate the effects of such governing parameters on the velocity and temperature fields. Comparison with previous results from the literature were also carried out in order to verify the computational code developed in this work. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
