Seminar - Spectral Properties and Models for Thermal Radiation from High‐Temperature Gases and Plasmas by Prof. Michael F. Modest

Date:

01 June 2012 (Friday)

Time:

11:00pm – 12:00pm

Venue:

EF305, The Hong Kong Polytechnic University

Abstract:
Predicting radiative transfer rates in high‐temperature reacting flows is an extremely difficult task, because the radiative transfer equation (RTE) is a five‐dimensional integro‐differential equation, and is exacerbated by the fact that radiative properties in reacting flows undergo extreme fluctuations across the electromagnetic spectrum. The problem encounters additional levels of difficulty in high‐temperature plasmas, as found in the hypersonic shock layer in front of spacecraft entering an atmosphere, leading to thermochemical nonequilibrium, and in the presence of turbulence, leading to highly‐nonlinear interaction terms. This talk will concentrate on spectral modeling of radiation from combustion gases and plasmas. The nature of radiative properties of high‐temperature gases and plasmas will be reviewed, followed by a discussion of traditional as well as modern spectral methods, with emphasis on recent work carried out by the speaker in the field of combustion and hypersonic plasmas. Finally, some application examples will be presented.
