The simulation was modeled with the following boundary conditions: Velocity inlet, and the outlet was modeled as wall (since there is no outflow). Fluent solved this scenario and gave the velocity profile and pressure profile result.<\/span><\/strong><\/p>\n<p><\/p>\n<p class=\"MsoNormal\"><strong>Since there is no outflow in the pipe, there should be no flow in the pipe, while the outflow is closed and the fluid is incompressible the change in the contour of velocity field appears.
