A turbulent combustion noise model
(Virginia Tech, 1989-05-05)
A turbulent combustion noise model based on first principles is developed in this thesis. The model predicts (1) the pressure time series, (2) Sound Pressure Level (SPL) spectrum, (3) Over-All Sound Pressure Level (OASPL), ...
Nonlinear finite element analysis of a laminated composite plate with nonuniform transient thermal loading
(Virginia Tech, 1988-03-25)
<p>Metal plates are being replaced by lighter but equally strong laminated composite plates in order to improve efficiency and increase performance of aerospace vehicles. But because of the complex construction of laminated ...
Simulation of an algorithm for the active control of combustion noise
(Virginia Tech, 1990-12-16)
The simulation of an algorithm for the active control of combustion noise generated by a turbulent flame produced by an open burner is developed in this thesis. The simulation includes (1) an autoregressive model of real ...
