Abstract
Finite-difference-like discretizations are developed for the time-depe ndent Navier-Stokes equations and the thermal energy equation on Delau nay triangulations of the how domain. The flow is assumed to be therma lly expandable; that is, the density varies only with temperature. A c haracteristic-like (CL) method is used to discretize the temporal and convective terms. The dual variable method reduces the size of the dis crete system by a factor of five.
