The only one time I succeeded to get results close to desirable happened with massflow at inlet and static pressure at outlet. Efficiency, compression ratio, pressure and temperature values were ok,...

I don't understand what do you mean by normalizing. Should I do it or is it solver task? Is it enough just to set these values (that correspond outlet...

I meant just to estimate static pressure and temperature approximately for each corrected massflow rate at the exit and use it as reference values. Of...

Well, if I propose static pressure and temperature at the outlet, will it help? Or even little mistake is not acceptable? I could get results as...

Well, I think it's possible that geometry mistake leads to flow separation and stall. But why mass corrected flow BC is not good? I read it works well and one can use it to get all machine speedline...

I tried it before. Total pressure at inlet, static pressure at outlet. I started from 200kPa at outlet, then increased it up to 300kPa (I can't find the results,...

About my task I use nominal rating rpm - 12010 rev/min to get two curves: pressure ratio vs massflow and efficiency vs massflow (as on pictures I added above). I have information about one regime...

Replies: 14 underestimated static pressure at axial compressor outlet Views: 1,527 Posted By Red Ember underestimated static pressure at axial compressor outlet Hi to all! I tried to simulate axial compressor, but got confusing results for static pressure and temperature. I used total pressure and total temperature at inlet and corrected massflow at exit....
