PIPE FLOW SIMULATION WITH LINE PROBE USING SOLIDWORKS.

AIM: TO RUN A PIPE FLOW SIMULATION USING SOLIDWORKS.

OBJECTIVE:

• To create the Pipe with three-line probes, enclosed by lids.
• To perform Flow simulation study.
• To obtain a plot for velocity variation at a cross section.
• To export the results to a spreadsheet.
• To create flow simulation at 85%,90% and 95% of pipe length for three conditions-

Study number	Reynolds number	Velocity (m/s)
1	100	0.00445
2	1000	0.0445
3	10000	0.445

OVERVIEW:

The purpose of this project is to illustrate the setup and solution of a 3D fluid flow in a pipe. The pipe networks are common in any engineering industry. It is important to know the development of a flow at the pipe entrance and pressure drop taking place along the pipe length. The flow of fluids in a pipe is widely studied fluid mechanics problem. The correlations for entry length and velocity profile are available in terms of flow Reynolds number.

CALCULATION:

Reynolds number, `Re= ρVD/μ`

Here,

ρ = Density of fluid (kg/m³)

V = Flow velocity (m/s)

D = Diameter of pipe (m)

µ = Dynamic viscosity of the fluid (pa.s)

here, Water is taken as a fluid so

ρ=1000 kg/m³

µ=8.9*10^-4 pa.s

D=0.02 m

Then we will get the values of V at different Reynolds number, as

For Re=100: V=0.00445 m/s

For Re=1000: V=0.0445 m/s

For Re=10000: V=0.445 m/s

PROCEDURE:

Firstly, we will create the pipe with line probes, as –

Then creating the lids, as –

To start the flow simulation, we will provide some initial conditions like Fluid type, Analysis type, Thermodynamic parameters etc.

Fluid type

Analysis type

Thermodynamic parameters

Now setting up the boundary conditions, as –

Static pressure

Velocity

Wall

Creating mesh

Now for result section we will select the line probe, as –

Selecting the Cut plane

Then by clicking on the “run”
