## Abstract This paper explores some numerical alternatives that can be exploited to derive efficient lowβorder models of the NavierβStokes equations. It is shown that an optimal solution sampling can be derived using appropriate norms of the NavierβStokes residuals. Then the classical Galerkin app

An adjoint optimization method, based on the solution of an inverse flow problem, is proposed. Given a certain performance functional, it is necessary to find its extremum with respect to a flow variable distribution on the domain boundary, for example, pressure. The adjoint formulation delivers the
Intensities and profiles of the Ha, H/3, H3,, K, and D3 lines are measured in a solar prominence. From the profiles of these lines we estimate T = 6400 K and vt = 5.7 km s -1. We construct a simple isothermal model which explains the Ha intensity and profile for an assumed total particle density nT
