Solutions, perfect fundamental properties

We have so far treated the quasi-one-dimensional flame as a constant pressure system with an interaction solely between chemical events and diffusion of matter and energy. Provided that the flame Mach number is low, this is a perfectly legitimate means of investigating the interaction per se, and it leads to a solution which includes the steady state, one-dimensional, laminar burning velocity. As an eigenvalue of the steady-state differential equations, the laminar burning velocity is a fundamental property which depends on the... 

Ideal Gases at High Temperature. Three fundamentally different approaches have been applied to the treatment of the turbulent boundary layer with variable fluid properties all are restricted to air behaving as an ideal, calorically perfect gas. First, the Couette flow solutions have been extended to permit variations in viscosity and density. Second, mathematical transformations, analogous to Eq. 6.36 for a laminar boundary layer, have been used to transform the variable-property turbulent boundary layer differential equations into constant-property equations in order to provide a direct link between the low-speed boundary layer and its high-speed counterpart. Third, empirical correlations have been found that directly relate the variable-property results to incompressible skin friction and Stanton number relationships. Examples of the latter are reference temperature or enthalpy methods analogous to those used for the laminar boundary layer, and the method of Spalding and Chi [104]. 

This chapter is dedicated to fundament the crystallographic approach of the solid state structure and properties by presenting the main features the geometric as well the d5mamical theory of X-ray diffractions may reveal for a perfect crystal. Here will be studied their fields and intensities, the equations that cormect them as also the solutions of propagation for the non-absorbent or respectively absorbent crystals the present discussion follows Putz and Lacrama (2005).
