Abstract
This article endeavors to figure a distinct numerical model. This can clarify and anticipate the arrangement of streamlines in an open-circuit stream over a rigid body. This paper speaks to an endeavor of ordinarily building up a brought together coordinated hypothesis dependent on a few halfway speculations from the surviving literature and experimental database of the fluid dynamics. The essential accentuation of this hypothesis is to see how streamlines are shaped and how the formation and adjustment in the streamline contribute to various phenomena, for example, flow separation, flow transition, down-wash, stalling velocity, effects of the camber and incidence angle on the flow. Though there is a ton of extant literature concerning streamlines, a numerical model which can foresee the directions of fluid particles and their effect on the stream is non-attentive. The proposed numerical model can clarify the development of streamlines with sufficient regard to the various fundamental geometric shapes in a Newtonian fluid. How to cite this article: George Y.

Highlights
Fluid dynamics remain a peculiar field of study as the fluid particles are very miniature in their dimensions along with negligible masses and the solid bodies interacting with them have a considerable mass and size
It is often ambiguous to identify which particular theories among classical mechanics, or quantum mechanics are applicable for a given model of a fluid dynamic system
In the context of Philosophy and History of the fluid dynamics, the approach of classical mechanics has been observed to be not very effective in describing and predicting an open-circuit flow.The popular Navier–Stokes equation is based on Isaac Newton’s second law to fluid motion, together with the assumption that the stress in the fluid is the sum of a diffusing viscous term and a pressure term describing viscous flow
Summary
Fluid dynamics remain a peculiar field of study as the fluid particles are very miniature in their dimensions along with negligible masses and the solid bodies interacting with them have a considerable mass and size. Depending on the various factors such as nature of the flowing fluid and nature of the fluid flow the forces acting efficiently on the body can be expressed as functions of fluid density(ρ) , dynamic viscosity of the fluid(μ) , free stream velocity(v∞) , effective Area(A)[8]. The resultant force is an aggregate effect of shear stress distribution and dynamic pressure of the fluid over the body[4][7] These do not give an explanation why and how the shape is affecting the flow. The vertical component of resultant force and horizontal component of resultant force namely Lift(L) and Drag(D) are traditionally written as shown in (5) and (6)[10][7] In these equations, the force due to shear stress is ignored, and equations show forces as a product of free stream dynamic pressure(q∞) and a reference area(Are f ). This will be helpful in order to predict the impact of the shape and size over the flow
