| Title | 262: Validation of GYRO | ||
| Name: | Ron Prater ( |
Affiliation: | General Atomics |
| Research Area: | Transport Model Validation | Presentation time: | Not requested | Co-Author(s): | Chris Holland, Anne White, George McKee |
| Description: | Recent work by Chris Holland and Anne White have shown that GYRO can predict accurately the heat transport at the mid-radius of an L-mode discharge. It would be a good step in the validation of GYRO to see whether the transport trends can be predicted as well. | ||
| Experimental Approach/Plan: | Starting from the well-studied discharge already studied, vary parameters that are known to affect the confinement time. For example, vary the plasma current up and down by 50% and change the heating power by 50% (but staying in L-mode). See if the experimentally observed trends in diffusivity and fluctuation parameters can be understood in subsequent GYRO calculations. | ||
| Background: | Build on success in modeling a simple case. Take small steps from an understood case before moving to discharges which are much more complicated. | ||
