Ansys Fluent - Computational Fluid Dynamics (CFD)

Learn how a nozzle increases velocity by constricting flow and applying the continuity equation A1 v1 = A2 v2, where the inlet area is larger than the outlet.

Import geometry into design modeler, convert to a solid nozzle, and mesh with structured, multi-zone, or tetrahedral methods, applying inflation for boundary layers and designating inlet/outlet regions for boundary conditions.

Import geometry, create a 2d triangular mesh in Ansys Fluent, refine elements to 0.002, and define inlet, outlet, and cylinder wall as named selections for a CFD run.

Visualize the flow around a cylinder by creating a plane, plotting velocity contour, and animating streamlines to analyze pressure distribution and recirculation region.

Import and modify the geometry by creating a ground clearance enclosure and subtracting the car body from the enclosure, enabling post-processing visualization for CFD analysis.

Perform meshing for the Ahmed model by generating a default mesh, sizing faces, and applying inflation to capture boundary layer effects for Fluent CFD.

Learn to set up boundary conditions in Ansys Fluent for a steady-state computational fluid dynamics analysis, including inlet velocity, frontal area, and drag and lift quotients.

Explore how wind turbine analysis in Ansys Fluent models fluid flow behind a turbine, examining velocity and pressure changes, and preview creating a rotating domain in the next video.

We set up the turbine CFD geometry by creating outer enclosures, adding a rotating cylindrical domain, and using Boolean operations to subtract the blade and define the rotating region.

Analyze transient results in Ansys Fluent by loading time-stamped results, visualize velocity and pressure in the stationary frame, and create animations of rotating turbine flow.

Explore a shell and tube heat exchanger in CFD, where ammonia vapor at minus 30 degrees Celsius exchanges heat with water at about 28 degrees Celsius under transient conditions.

Import the GMAT and set up the geometry for a heat exchanger in Ansys Fluent, renaming the shell and fluid domain to define the flow path.

Define manual contact interfaces between shell, tube, and fluid domains to mesh a heat exchanger in Ansys Fluent. Set shell and fluid element sizes and evaluate mesh quality for convection.

Load the saved time steps from the heat exchanger data to generate results, set temperature controls and probes, and analyze inlet and outlet temperatures with volume rendering and animation.

Import geometry and generate a 2d triangular mesh with element size 0.002, apply smoothing, and name the water inlet, oil inlet, and outlet to prepare for a multiphase CFD setup.

covers setting up a three-phase multiphase flow simulation in Ansys Fluent, defining oil, water, and air volumes, surface tension, boundary conditions, inlets, initial patching, and time-step parameters.

Shows multi-phase flow results of water and oil mixing in a tank, with green representing water and the oil on the right, driven by gravity and phase interaction.
