Abstract: In this article, we describe the use of proper orthogonal decomposition (POD) to investigate how the dominant wake structures of a bluffbodystabilized turbulent premixed flame are affected by the heat released by the flame ...

Abstract: The predictive capability of the lattice-Boltzmann very large eddy simulation (LBM-VLES) methodology was evaluated for industrial gas turbine exhaust diffuser-collector applications. The effort focused on evaluating the ...

Abstract: The study presented in this article provides detailed description about a newly developed experimental technique to determine three key convective heat transfer parameters simultaneously in hot gas path of a modern high ...

Abstract: This paper describes studies completed using a quarter-scaled rig to assess the impact of turbine exit swirl angle and strut stagger on a turbine exhaust system consisting of an integral diffuser-collector. Advanced testing ...

Abstract: In this article, we describe a novel use of proper orthogonal decomposition (POD) for validation of the structure of dominant flow features in the wake of a bluffbody flameholder. Largeeddy simulations (LES) using both ...

Abstract: The ever-increasing combustor exit temperature in modern turbine engine designs raises cooling challenges for the nozzle guide vane (NGV). Due to the complexity of NGV cooling design, the cooling effect from the upstream ...

Abstract: Recent cutting-edge designs for gun barrels, projectiles, and propellants require testing, such as measuring the internal pressure during firing. However, there are concerns with the current drilling method to mount pressure ...

Abstract: Although the thermal-barrier coating (TBC) can protect the gas turbine components from the hot mainstream gas, it is not uncommon that the TBC partially blocks the film cooling holes during the spraying process. The film ...

Abstract: Linear turbine cascades have been widely used to conduct fundamental and applied investigations, but only a few transient test facilities with the linear turbine cascade are available in the open literature. A novel transient ...

Abstract: Contemporary tools for experimentation and computational modeling of unsteady and reacting flow open new opportunities for engineering insight into dynamic phenomena. In this article, we describe a novel use of proper ...
