ANSYS Fluent Flow Project
Budget: $10 – $30 USD
consider the flow of room-temperature water in such a pipe of length L = 40.0 cm and diameter D = 1.00 cm. Assume the water enters the pipe at a uniform speed equal to V = 0.05024 m/sec. From property tables, one finds the kinematic viscosity of the fluid as ν = μ/ρ = 1.005 x 10-6 m2/sec. Calculate the Reynolds number
to confirm that the flow is laminar and give reason(s). It is assumed that the fluid exits the pipe
at the pressure of the atmosphere. For EACH of the following mesh selections in FLUENT (note
and report the number of elements for each mesh type),
1. Very Coarse Mesh
2. Coarse Mesh
3. Medium Mesh
4. Fine Mesh
5. Very Fine Mesh
6. Ultrafine Mesh
Obtain the solution to the fluid dynamics problem in the full pipe by numerical means to generate
the velocity distribution in the pipe. Once you have obtained “converged solutions” (you must
document and explain what “converged” means) for each mesh type, program FLUENT to
generate the following plots:
1. Plot the dimensionless distance r/D (vertical axis) against Vz/V where V is the entrance
velocity as given. Generate the plot at axial dimensionless positions (z/D) of 1 and in
increments of 1 until 20, and at the pipe exit, z/D = L/D = 40. Superimpose the analytical
solution obtained in class on the L/D = 40 plot.
2. Program FLUENT to generate the pressure drop from z/D = 1 and z/D = 20 locations for
all mesh options. Plot the pressure drop values (vertical axis) against the number of
elements (cells) in each mesh option.
3. Produce any other plots that you think can enhance the learning value of this exercise.
Write a technical report using ASME style of writing on the results obtained, the analysis
of the results and the lessons learned from the exercise. It is not enough to say “the results
make sense”; dig a little deeper to interpret the results to convince your colleagues
(including faculty!!!!) that you understand what has been produced from the analysis.
Your report must be typed (with lots of figures!!!!!), single spaced, 12 point Times Roman
font with a Title Page, Abstract, Introduction, Problem Statement, Analysis of Results,
Conclusions, References sections at the minimum.
