need help! range of y plus and results of simulations
my simulation is about:
1. plain tube 2. turbulent flow 3. standard k - epsilon model 4. the working fluid is water 5. near wall treatment (STANDARD WALL FUNCTIONS) my problems are: 1. i get y plus in range 19 - 20, while for standard wall functions y plus must be 30 - 60, how to increase y plus for getting y plus range in standard wall functions ? 2. what is the best mesh for circular tube? many thanks for the help :) |
Double your mesh first cell height
