| Summary | 0002612: In twoPhaseEulerFoam Ergun drag correlation is calculated wrongly | ||||
| Description | In the calculation of the ergun drag in twoPhaseEulerFoam (4/3) is multiplied to the drag. This is needed as the general drag gets multiplied with 0.75. In the case of the ergun drag this is not needed and should be neglected by the 4/3. However, at least on my platform 4/3 is an integer division which produces unity. Hence has no influence on the value of the drag. Like this the calculated value is too low. The problem can be solved by replacing 4/3 with 4.0/3.0 | ||||
| Steps To Reproduce | Run any simulation using th Ergun drag modeling | ||||
