Goal: In these power point presentations, the basics of applied CFD simulation in the industry using powerful ANSYS-FLUENT software is presented.

1. ANSYS Fluent (basic)
Module 10
Instructor:
Dr. Mohammad Jadidi
(Ph.D. in Mechanical Engineering)

2. We'll solve this problem numerically using ANSYS Fluent. We'll look at the following results:
•Velocity vectors
•Velocity magnitude contours
•Pressure contours
•Velocity profile at the outlet
We'll verify the results by following a systematic process which includes comparing the results with the analytical solution in the full-developed
region.
Problem Specification
This module is drawn from MAE 4230/5230 Intermediate Fluid Dynamics at Cornell University.
Consider fluid flowing through a circular pipe of constant radius as illustrated below. The figure is not to scale. The pipe
diameter D = 0.2 m and length L = 3 m Consider the inlet velocity to be constant over the cross-section and equal to 1 m/s. The
pressure at the pipe outlet is 1 atm. Take density ρ = 1 kg/ m 3 and coefficient of viscosity µ = 2 x 10 -3 kg/(m*s). These
parameters have been chosen to get a desired Reynolds number of 100 and don't correspond to any real fluid.

8. Problem Specification
A fluid enters a pipe of radius 0.06 meters at a constant velocity of 0.1 m/s. The fluid has a density of 1.2 kg/m^3,
a thermal conductivity of 0.02 W/mK, a specific heat of 1000 J/kgK, and a viscosity of 1.8e-5 kg/ms. The first 5.76
meters of the pipe are isothermal, held at 300 K. The remaining 2.88 meters of the pipe have a constant heat flux
of 37.5 W/m^2 added at the wall.
Using ANSYS FLUENT, simulate the above flow. Calculate and plot the velocity, temperature, pressure and Nusselt
number variation in the pipe.
