    Notes: A generalized unstructured mesh generation procedure using Delaunay triangulation has been developed for adaptive finite element applications. The main features of the method include: (i) a fast and efficient initial triangulation; (ii) interior node insertion with good control over the grid size and aspect ratio distribution; (iii) a flux-based error across element boundaries. The scheme has been applied successfully to heat transfer problems involving steep temperature gradients. © 1997 John Wiley & Sons, Ltd.

    Laminar flow and heat transfer over a two-dimensional triangular step (1989)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 9 (1989), S. 1165-1177

    Notes: The velocity correction algorithm is used in the finite element method to solve forced convection problems between parallel plates with a triangular step, for Reynolds numbers up to 1000. Equal-order interpolation functions for velocity, pressure and temperature are used. The solutions show a smooth variation of pressure. The streamfunction, isotherms, isobars and velocity profiles are presented for a typical Reynolds number of 500. The skin friction and heat transfer results are presented for Reynolds numbers up to 1000.
