Hi every one

I want PHOENICS to calculate heat transfer coefficient for my case study. I choose the "ON" for "HEAT TRANSFER COEF" and "STUNTON NUMBER" from following path in PHOENICS main menu: "menu/output/wall fuction printout" But when I run the program I see heat transfer coefficients are zero every where of fluid domain. What's wrong with it? Isn't it enough? What another thing I must do?

Best Regards

This can happen if the case is laminar,because the heat transfer coefficient and stanton number are computed via wall functions, and these are not visited in laminar flow. A way around the problem is to set ENUT=1.E-10, because this will then trigger the wall functions.

please send me the heat transfer coefficients of common materials like ss,ms, etc.

Where are you setting the HTC and Stunton Number in the VR-Editor? What version of Phoenics do you have?

I want to know what is the heat transfer coefficient of polyatyrene and the chipboard

hi everyone i want to estimate the heat transfer coefficient for molten aluminium bath for my heat treatment process. i've heated my samples in molten aluminium bath at 880 degree of C

hi to all.ive got a hw to do which needs to use the heat transfer coefficients of ait at different tempratures. i know theres a formulla but will you please send me a table if theres any at all?its urgent & i have to get this done soon

hi ali.are you iranian? do you work with phoenics in heat transfer?can you help me to solve my problem? stsnton nu. is very high and i dont know what.thank you

what is heat transfer coefficient & formulaie
