Abstract In the hot plasma simulations when the main flow is modeled by two‐temperature Euler equations, it is often useful to deal with slowing down of suprathermal particles created by fusion. Then a kinetic equation has to be addressed for these particles. We focus in this paper on the coupling between the fluid model and the kinetic equation; specially details for a coherent treatment of the electrostatic field are given. We emphasize some details of the numerical simulations and we give numerical results. Copyright © 2008 John Wiley & Sons, Ltd.
