i tried running the code following every instruction in this tutorial but i had an error addressed below ''Undefined function 'BEMFunction1' for input arguments of type 'double'. Error in Untitled2 (line 25) [Efficiency(i), Power(i), RPM(i), Torque(i), stall(i) ] = ... '' how can i solve this please?
Can you plz post video on making a matlab program? (1) calculates the wake loss of a downstream turbine for a given ambient turbulence and wind speed and RD(rotor diameter) that is positioned downstream such that the effective turbulence (i.e. I_eff =0.14) criteria is just respected. Then making a sensitivity of how the wake loss changes by increasing turbine spacing by 1 RD. Thanks!!
It is very interested tutorial ! Sr, how can we simulate the performance of VAWT based on Double Multiple Stream Tube model? I hope you will respond it soon in your TH-cam channel . thank you!
hi >> thanks for these useful projects .. i'm working on project about Brushless Doubly fed induction wind generator . I have difficulties in modelling and simulating the steady state equations model in Simulink .. Can you make a Lesson about it ?? or if you have an email so that I can stay in touch with you about this and thank you
hello sir my code isn't running it shows error in==> at 19 VTip= TSR(i)*VWind..please help me sir.. please reply ..it would really help me if you reply to my comment..?
"zeros(a,b)" creates an array with "a" rows and "b" columns of zero. "zeros(1,5)" is this same as [0,0,0,0,0], it has 1 row and 5 columns of the number "zero". An array of zeros can act as a blank list that will later be populated by some other process; in this case, we populate them with a for loop. pre-creating arrays of zeros for your variables is similar to initializing variables in other programing languages. While not necessary in this case, creating the arrays of zeros before the for loop allows matlab to reserve the right amount of memory for your variables up front, instead of incrementally making more room for them as the for loop runs, which is a little slower. Also, type "help zeros" in the command window.

@Milo DiPaola, you did a very nice job , can you please send me the code of the BEMfunction1, how have you calculated the efficiency , power, RPM, torque, and stall ? what is this R stand for ? and how have you got this R. my email is mphilbertt@gmail.com
I have received many requests for the BEM code. This code was written for students at UMass Lowell and was not intended to be distributed. After so many requests I will make a version for distribution and post a link to it here. If a link to the code is not in the description by August 1st 2018, feel free to request the code in the comments.

how can i solve this please?
Is this for ideal blade design or actual ???
Like others, it seems a very usefull matlab-tutorial. Would it be possible to post the used functions?

I would like to know how to program the thermal efficiency of Brayton's real cycle of a solar gas micro-turbine. Thanks
Kindly how u get efficiency, RPM, Torque,Power and stall?
Thank u very much for this useful video / please how u get R? And what represent ?
what is the code of BEMFounction ?

Dear Milo, can you post the code for the function BEM please?
Hello sir, could you upload or share this mathlab file(simulink)... im student and i want to learn this simulation, for my learner... thank you sir
Who figured out the BEMFunction issue? or does anyone have the file?

Can you explain what the zeros function does?
