A review of Cartesian coordinate construction from a sphere, for generation of two dimensional geological net projections

The technique of great circles, small circle, and net construction is described and reviewed. The FORTRAN program NET will plot accurate Orthographic, Wulff, Schmidt and Kavraiskii nets. The nets may be constructed with any diameter between 2 and 30 cm; they may be horizontal or inclined at any angle and are drawn in several pen colors. Nonstandard FORTRAN and system specific library subroutines used are listed.

Heterogeneous/homogeneous reactions and transport coupling for catalytic combustion systems: a review of model alternatives

In applying catalysis to real combustor applications the modeling of transport and chemistry interactions can be key to understanding combustion characteristics. For example the effect of boundary-layer flow and heterogeneous /homogeneous chemistry can determine product selectivity for catalytically promoted oxidation of chlorinated hydrocarbons. In this paper we discuss parameter regions where different flow models including lumped-parameter-transport laminar boundary-layer and full twodimensional models can be used for obtaining design insights. The degree of detail required in the gas phase chemistry models and surface chemistry models depends both on the system and the properties to be predicted. Definition of different regimes of operation and limits of applicability for parameric scaling relationships are key to the design of catalytic combustors for incineration or power generation. In addition, a theoretically-based rational strategy for applying catalytic boundary conditions in turbulent flow models would provide a valuable design tool. Examples of alternative modeling strategies are given below along with possible applications for the design of practical catalytic combustion systems.
