Question & Answer to the Presentation

Question from Mr. Istianto Budhi Rahardja 2020.11.18 14:52:11 Thank you for your question 1. soft ware use for simulation is Computational Fluid Dynamics (CFD) 2. Tim for simulation is 10 menit for 1 iteration. 3. With angle 56.5 make velocity magnitude that happened is flow more completely and immediately spins the turbine. This angle make homogen flow than angle 46.6. Replies:

Question from Mr. M. Muchammad 2020.11.18 14:12:49 1. what software is used for simulation? 2. how much time for simulation? 3. Why does the velocity magnitude at angle 46.6 to 56.6 is decrease?
