Turbine-Based Combined Cycle (TBCC)
Engines
Investigator: Vivek Gautam
Overview
The
main focus of our work is to provide comprehensive experimental database that
can be used to design robust, efficient, smaller and low emission combustors for
Rocket and Turbine-Based Combined Cycle (TBCC) engines. The database can also be
used for validation of various CFD models developed to predict performance of
such engines. In parallel to the experimental studies we are also developing
modeling tools to study the flow and thermal characteristics of gaseous and
liquid hydrocarbon flames at various inlet and operational conditions. The
experimental facility and modeling efforts will allow us to examine the flow
characteristics, species distribution inside the combustor, thermal field
uniformity and heat transfer to combustor walls. The results obtained from the
models will be used to design scaling laws for critical flame parameters, such
as, flame length, blow-off limit, combustion efficiency and pattern factor over
a range of flight conditions.
