Scientific Essay from the year 2015 in the subject Physics - Other, Khulna University, course: Mathematics, language: English, abstract: Velocity profile and temperature distribution of a viscous incompressible fluid along a semi-infinite vertical plate with large suction is investigated in this work. The governing equations are solved numerically using perturbation technique. The flow phenomenon has been characterized with the help of flow parameters such as Suction parameter , Prandtl number and Eckart number .The effects of these parameters on the velocity field and temperature distribution have been studied and the results are presented graphically and discussed quantitatively. This type of problem is significantly relevant geophysical and astrophysical studies.
