Book Description
Molecular Physics and Hypersonic Flows bridges the gap between the fluid dynamics and molecular physics communities, emphasizing the role played by elementary processes in hypersonic flows. In particular, the work is primarily dedicated to filling the gap between microscopic and macroscopic treatments of the source terms to be inserted in the fluid dynamics codes. The first part of the book describes the molecular dynamics of elementary processes both in the gas phase and in the interaction with surfaces by using quantum mechanical and phenomenological approaches. A second group of contributions describes thermodynamics and transport properties of air components, with special attention to the transport of internal energy. A series of papers is devoted to the experimental and theoretical study of the flow of partially ionized gases. Subsequent contributions treat modern computational techniques for 3-D hypersonic flow. Non-equilibrium vibrational kinetics are then described, together with the coupling of vibration-dissociation processes as they affect hypersonic flows. Special emphasis is given to the interfacing of non-equilibrium models with computational fluid dynamics methods. Finally, the last part of the book deals with the application of direct Monte Carlo methods in describing rarefied flows.

Book Description
A series of diagnostic experiments have been compiled to investigate rf and microwave discharges in N2, such as those used for plasma processing of electronic materials. To develop a picture, as complete as possible, of the discharge chemistry, several reactive intermediates, e.g. N, N2(A), N2(B) and N2(C), were monitored. An alternative two-photon laser induced fluorescence (TALIF) scheme for detection of atomic nitrogen has been characterized and used to monitor and evaluate various atomic nitrogen sources. Photodissociation of N2O and subsequent detection of N atom photofragments by TALIF was also performed using the 207 NM laser pulse. From measurements within the pulsed rf discharge, a kinetic model was developed which predicted absolute concentrations of various discharge species. The behavior of several discharge species were also monitored in the N2 microwave discharge and compared to the model for the addition of small amounts of H2 and NH3. Atomic nitrogen destruction by surface and volume reaction was investigated by temporal N atom decay within a pulsed rf discharge. The volume loss rate of atomic nitrogen was also quantified to be substantially increased with the addition of as little as 0.1% O2 in an N2 rf discharge.
