This is the 1st MATLAB App in the Virtual Thermal/Fluid Lab series.
This MATLAB App allows you to:
1. Visualize a boundary layer
2. Study the growth of boundary layer thickness in response to free-stream velocity
3. Visualize streamlines and velocity profile
4. Learn how to solve boundary layer problem numerically with TDMA
5. Look at the GUI source code and see how it is created
Check out the webinar on virtual fluid mechanics and heat transfer labs with MATLAB:

Absolutely love this! However, how to port this into current Matlab App Designer? I want to do similar work with physical simulations but using the newer App Designer and sadly almost all examples are not of the nature like this example (which is perfect). Anyway you could port this to App Designer and make it available? Or point to something in App Designer that uses ODEs or PDEs? Thanks So much!
Hi! How can I adapt this for the following conditions: stationary bottom plate, upper plate moving at an initial velocity U, with different pressure gradients? I'd like to observe what the plot of the velocity profile would look like against the vertical axis set by the height of the channel.
hi, how can i add the energy equation to this code and solve for the temperature profile??
hi, great work!
can u plz hepl me to find app to solve two-phase fluid flow in the pipes?
i have very important work to realise in this days. TNX
Hi, Great work!, I am trying to model Shock wave boundary layer interaction, can u plz help me the built the Matlab code. my email@example.com
Hi Ye Cheng, Excellent work! Wondering if you can please solve this velocity profile/boundary layer problem numerically using finite different methods? Can you please share the Matlab code for that?
can u plz give me the equations what u used in the boundary code
can u plz give me the code for unsteady flow about a stagnation point on a stretching sheet in the presence of variable free stream
plz give me code for this.
boundary conditions are X2^(R+1)(0)=1;X2^(R+1)(@)=lamda;X4^(R+1)(0)=1;X4^(R+1)(@)=0;X1^(R+1)(0)=0;
where pr=0.72,h=0.01,lamda=0.1,alpha_star varies from 0 to firstname.lastname@example.org,eta will end when X2=lamda,X4=0;R is iteration and i is position
plz help me in this writing code
@kolla VASU, you can download all code by clicking on the "Download Zip" button.
plz send the matlab code for this
i have some equations how can i solve by TDMA solver code plz
The idea is conveyed perfectly! This demo convinces one that teaching fluid mechanics, heat transfer and other similar courses without help of matlab could be deficient.
Great job Ye.
Click on the 'Open Code' button in the app, and you will see a script (boundaryLayerScript.m) that shows the algorithm behind and how A,B,C,D are constructed based on the x-momentum equation. This topic can be found in many textbooks, such as Computational Heat Transfer by Yogesh Jaluria (page 244, similar but not identical).
Hi, I would like to know what are the equations that you use to fill each diagonal A, B and C and also the RHS vector D.
