Abstract: The mechanical stiffness and damping coefficients of a spring-suspended deck section model in still air are conventionally assumed to be constants and can be extracted through free decay vibrations. The extracted stiffness ...

Abstract: This article proposes a rotordynamic identification method using the accelerating sweep frequency excitation method. The computational fluid dynamics transient solution combined with the moving grid method is utilized to ...

Abstract: This paper presents a numerical investigation on the unsteady fluidelastic forces of tube arrays. The key focus is on the consistency between the unsteady fluidelastic force model and the quasi-steady model for tube arrays ...

Abstract: This paper presents the turbine blade leading edge model film cooling effectiveness with shaped holes, using the pressure sensitive paint (PSP) mass transfer analogy method. The effects of leading edge profile, coolant to ...

Abstract: A low-frequency continuous torsional motion technique (CTMT) is presented to efficiently extract the aerostatic force coefficients (AFCs) of bridge decks. In contrast to the conventional numerical simulations at a series ...

Abstract: This study investigates the effects of blowing ratio, density ratio, and spanwise pitch on the flat plate film cooling from two rows of compound angled cylindrical holes. Two arrangements of two-row compound angled cylindrical ...
