IIST Shock tube
This facility is a part of the High speed flow lab at IIST. A shock tube can be used for generating controlled shock waves using which gases can be heated to high temeperature
Gas temeperatrues as high as 2200K can be reaslised using the IIST sock tube. Due to its modular design the facility can be operated as a shock tube, supersonic tunnel and a shock tunnel. A Mach 3.5 contoured supersonic nozzle with an optically accessible 2D test section is also available for integration with this facility. The facilty is instrumented with dynamic pressure sesnors, high speed data acquisition system and a high speed schlieren system. Ongoing research activities in this lab are listed bleow
- Study of non-ideal effects in shock tube flows
- Development of TDLAS based diagnostics for shock tube
- Unsteady force measuremtns using strain gages
Laser absorption spectroscopy lab
This lab focuses on the development of sensors based on Tunable Diode Laser Absorption Spectroscopy(TDLAS). These non intrusive sensors have a wide range of applicaitons and we
are currently focusing on application to Combustion research, High enthalpy flows and atmospheric sensing.
Tunable DFB diode lasers are used to traget the absorption features os species such as H2O, O2 and CH4 in order to measure the gas temperature and species concentration. The ongoing sensor development work is listed bleow
- HIgh speed TDLAS for shock tube flows
- Trace gas TDLAS sensing with multi-pass cell
- WMS based sensing for high pressure applications
