This study was conducted for verification and systematization of estimation method about the headloss using CFD. Head loss which happens between the inlet and outlet of in-line mixer can be a major factor for the design and construction. Also, this case study about the sensitivity related to the velocity in the piping system. As result, program's default calculation function was used to get each side's total pressure and the differential of each total pressure could be defined as head loss from in-line mixer. In the case of adopting pipe surface friction factor and geometry loss, Calculation residual can be much more reduced. It was found that residual of value between CFD method and field test ranged about 3 through 18 percent. |
