Description
Summary:There are two main objectives in this paper. One is to find sufficient conditions to ensure the existence of weak solutions for some bidimensional thermoelectric problems. At the steady-state, these problems consist of a coupled system of elliptic equations of the divergence form, commonly accomplished with nonlinear radiation-type conditions on at least a nonempty part of the boundary of a C1${C^{1}}$ domain. The model under study takes the thermoelectric Peltier and Seebeck effects into account, which describe the Joule–Thomson effect. The proof method requires a fixed point argument. To this end, well-determined estimates are our main concern. The second objective of the paper is the derivation of explicit W1,p${W^{1,p}}$-estimates (p>2)${(p>2)}$ for solutions of nonlinear radiation-type problems in the general n-dimensional space situation, where the leading coefficient is assumed to be a discontinuous function on the space variable. In particular, the behavior of the leading coefficient is conveniently explicit on the estimate of any solution.
