Dynamic Simulation and Control of Chemical Processes

Dynamic Simulation and Control of Chemical Processes - using MATLAB & Simulink

Home -> Lecture Notes -> MATLAB & Simulink

The following are some of the models that I have developed and solved using MATLAB & Simulink.

Examples from Chemical Reaction Engineering
1	Solving simultaneous differential equations: tworxns.m; tworxns.mat
2	Dynamics of Semibatch Reactor: semibatch.m
3	Dynamics of CSTR: cstrrxns.m; cstrrxns.mat
Examples from Chemical Engineering Thermodynamics
4	Using two dimensional interpolation function 'interp2' to find Compressibility Factor(Z) of a gas Zvalue.m; CompressFactor.mat
5	Volume of Nonideal gases from Various equations of State: assign1.m; pvt_data.mat; v_vander.m; v_redlich.m; Z.m; pvt_result.mat; pvt_result.dat
6	Bubble point & Dew point calculautions: sat_pr_antoine.m - Vapor pressure from Antoine equation sat_temp_antoine.m - Saturation temperature from Antoine equation BUBL_P.m - Bubble point vapor composition and Pressure BUBL_T.m - Bubble point vapor composition and Temperature DEW_P.m - Dew point liquid composition and Pressure DEW_T.m - Dew point liquid composition and Temperature

Instructions for using these files (for the beginners):

If these files are opened as text files by your browser, just save them as .mdl files.
Using Simulink you can open the files, and run the simulation to get the results.
The results are in the form of either display in scope or as output to a .mat file.
In case of scope output just doubleclick the scope-icon to get the graphical output.
In case of .mat file output, from Matlab command prompt, issue the command load filename and then type the variable name to get the output. These variable name is obtained by seeing the paramaters in the .mat file.
