f*x 发帖数: 7 | 1 Plasmas are considered cold when the flow velocity is much larger
than the thermal velocity, warm when the two velocities are roughly
the same, and hot when thermal velocity dominates over the flow velocity.
Concerning your second question, what is the mass of plasmas? Very very little,
right? ( you can estimated it based on ionization rate, flow rate, the volume
of plasma zone, the pressure of your chamber),the degree of heat transfer
not only depends on temperature difference, but on its mass |
