1,Velocity components:u = a 2 ( b cx )2v = 2cby + 2c 2 xy(2)ba c y=0(3)Setting these to zero and solving simultaneously yieldsStagnation point:0 = a 2 ( b cx )2x=v = 2cby + 2c xy 2So, yes there is a stagnation point its location is x = (b a)/c, y = 0. At any point (x,y) in the flow field, the velocity components u and v are obtained from Eq.

2 The flow is two-dimensional in the x-y plane.AnalysisThe velocity field is() ()V = ( u, v ) = a 2 ( b cx ) i + 2cby + 2c 2 xy j 2(1)At a stagnation point, both u and v must equal zero. If so, we are to calculate itsAssumptions1 The flow is steady. Chapter 4 Fluid Kinematics 4-4 Solution location.For a given velocity field we are to find out if there is a stagnation point. If you are a student using this Manual, you are using it without permission. Limited distribution permitted only to teachers and educators for course preparation. In some flow fields there is more than one stagnation point.4-2 PROPRIETARY MATERIAL. Discussion If the flow were three-dimensional, we would have to set w = 0 as well to determine the location of the stagnation point. 2 The flow is two-dimensional in the x-y plane.AnalysisThe velocity field is V = ( u, v ) = ( 0.5 + 1.2 x ) i + ( 2.0 1.2 y ) j(1)At a stagnation point, both u and v must equal zero. 2 by plugging in x = 0 and x = L.4-3 Solution location.For a given velocity field we are to find out if there is a stagnation point. 1 becomes u = uentrance +Parabolic speed:( uexit uentrance ) L2x2(2)DiscussionYou can verify Eq. 1 is satisfied by setting c = 0, a = uentrance and b = (uexit - uentrance)/L2. 3 The water is incompressible.AnalysisA general equation for a parabola in the x direction isu = a + b ( x c)General parabolic equation:2(1)We have two boundary conditions, namely at x = 0, u = uentrance and at x = L, u = uexit. 4-2 Solution We are to write an equation for centerline speed through a nozzle, given that the flow speed increases parabolically.

Discussion Fluid kinematics deals with such things as describing how a fluid particle translates, distorts, and rotates, and how to visualize flow fields. Fluid kinematics deals with describing the motion of fluids without considering (or even understanding) the forces and moments that cause the motion. Fluid kinematics is the study of how fluids flow and how to describe fluid motion. Chapter 4 Fluid Kinematics Introductory Problems4-1C SolutionWe are to define and explain kinematics and fluid kinematics.Analysis Kinematics means the study of motion.
