Fluid #2: Flow Around A
Baseball USING FLOTRAN**

**
Introduction: **
In this example you
will model air flow over a baseball.

**
Physical Problem:
**Compute and plot
the velocity distribution over the baseball shown below.

**
Problem Description:**

·
A
Baseball is **7.48 cm in diameter**. **(radius of 3.74cm)**

·
The
flow **velocity (of air) over the baseball is approximately 40 m/s**.

·
Objective:

To **
plot the velocity profile around the ball**.

To **
graph the velocity distribution above and below the ball**.

·
You are
required to **hand in print outs for the above**.

·
Figure:

**
**

**
IMPORTANT:
**Convert all
dimensions and forces into SI units.

·
Create
the larger area, then the area defining the baseball.

·
Subtract the baseball area from the larger area.

·
Define
the Element Properties as a 2D **Air** Element

·
Define
the Material Properties of the **Air** Element (Density and Viscosity
are the important qualities)
