Development of an infrared gaseous radiation band model based on NASA SP-3080 for computational fluid dynamic code validation applications
The increased use of infrared imaging as a flow visualization technique and as a validation technique for computational fluid dynamics (CFD) codes has led to an in-depth study of infrared band models. The ability to create fast and accurate images of airframe and plume infrared emissions often …

A Monte-Carlo-based simulation of jet exhaust nozzle thermal radiative signatures
… to overall observability is an aircraft’s infrared signature, particularly the infrared emissions from the exhaust nozzle and plume. This creates the need for accurate modeling of the infrared signatures from these sources as a design aid or for comparison of candidate designs. To that end, …

The Development of a Monitoring and Control System for a Pulverised Coal-Fire Burner Using Neural Network Approach
… "poor" combustion conditions were obtained. The infrared emissions from the flame, the combustion noise and the acoustic emission generated in the burner body were measured with appropriate sensors, as were the fuel and airflow rates and pollutant emissions. The signals from the sensors were …

Modeling the Energetics of the Upper Atmosphere
… above 100 km. It is an efficient emitter in the infrared where the thermosphere is optically thin, and serves as an important source of radiative cooling between 100 - 200 km. The primary mechanism of this cooling involves the conversion of kinetic energy from the background atmosphere into …

Modelling Mesopause OH* Emissions using a Global Circulation Model
… region of the atmosphere is dominated by the infrared emissions from vibrationally excited hydroxyl (OH*) radicals at ~87km altitude. These emissions provide a signal from which the behaviour of the middle atmosphere can be studied and in recent years a wealth of observational data on the …
