This dissertation is dedicated to the development and analysis of finite volume numericals chemes for convection-diffusion equations, which notably occur in models arising from physics and biology. We are more particularly interested in preserving asymptotic behavior at the discrete level. This dissertation is composed of three parts, each one including two chapters. In the first part, we consider the discretization of the linear drift-diffusion system for semiconductors with the implicit Scharfetter-Gummel scheme. We focus on preserving two kinds of asymptotics with this scheme : the long-time asymptotic and the quasineutral limit. We show discrete energy–energy dissipation estimates which constitute the main point to prove first the large...
