Fundamental concepts of two major subjects involved in the analysis of closed combustion systems: the aerodynamics of turbulence in the physical space (in Part 1), and the thermodynamics of exothermicity in the phase space (in Part 2), are exposed. Of principal significance to the former are the analytical properties of the principal two field elements: the rotational component of turbulence and the irrotational component of exothermicity. Direct implementation of this principle is provided by the random vortex method, illustrated here by solutions of simple two-dimensional, planar cases. Salient features of the latter are expressed in terms of the thermodynamics parameters, the thermostatics and the thermokinetics. Most instrumental for the first is the concept of the Le Chatelier diagram displaying the loci of states of the system components in terms of the relationships between the internal energy and the product of pressure and specific volume. The second provides a solution of the inverse problem in terms of an analytic expression for fuel consumption as a function of the measured pressure profile. The third furnishes a description of the system behavior in terms of its dynamic features: the amount (akin to displacement), rate (akin to velocity) and the change of rate (akin to acceleration).
