We explore the steady-state solution to the Braginskii equations and find the parameter regime in which a significant temperature difference between ions and electrons can be sustained in a driven steady state. The threshold for this effect occurs at [Formula: see text]. An analytic, leading order low flow solution is obtained, and a numerical, moderate Mach number [Formula: see text] is investigated. The limitation is found to be at moderate Mach numbers.}, year = {2022}, journal = {Physics of Plasmas}, volume = {29}, number = {8}, pages = {082302}, month = {aug}, issn = {1070-664X, 1089-7674}, doi = {10.1063/5.0101271}, }
