How would you approach the problem of plasma flow control in an experimental setup?

Sample interview questions: How would you approach the problem of plasma flow control in an experimental setup?

Sample answer:

1. Understand the Fundamental Physics of Plasma Flows:

2. Begin by gaining a comprehensive understanding of the underlying physics governing plasma flows, including magnetohydrodynamics (MHD), kinetic theory, and wave-particle interactions. This knowledge will serve as the basis for developing effective control strategies.

3. Characterize the Plasma Flow:

4. Conduct detailed diagnostics to characterize the plasma flow in the experimental setup. Measurements of plasma parameters such as density, temperature, velocity, and magnetic field provide valuable information for understanding flow behavior and identifying potential instabilities.

5. Develop Theoretical and Numerical Models:

6. Develop theoretical models based on fundamental plasma physics principles to predict flow behavior and assess the impact of various control strategies. Utilize numerical simulations to validate these models and gain insights into complex nonlinear dynamics.

7. Design Control Mechanisms:

8. Explore various control mechanisms based on theory, simulations, and experimental observations. These mechanisms could involve manipulating plasma parameters, applying external magnetic fields, or injecting neutral gas or energetic particles.

9. Implement Control Techniques:

10. Implement the designed control mechanisms in the experimental setup. This may require modifying the experimental apparatus, integrating control sy… Read full answer
