Boundary condition effects on vibrating cantilever beams
… traditional engineering approaches. By utilizing boundary controls which acted only when a flexure reached a certain deflection, the original purpose of the device could be preserved while also reducing or eliminating the risk of failure from plastic deformation or brittle failure. By starting …

Quantification of the Fire Thermal Boundary Condition
The thermal boundary condition to a fire exposed surface was quantified with a hybrid heat flux gage. Methods were developed to determine the net heat flux through the gage, incident heat flux, cold surface heat flux, convective heat transfer coefficient, adiabatic surface temperature, and the …

Electromagnetic scattering simulations using equivalent boundary condition models
Equivalent boundary condition models are one approach to simplifying electromagnetic (EM) scattering problems while retaining a high degree of solution accuracy in the domain of interest. These models are successful when the dominant EM characteristics of the scattering body are captured within the …

Acoustic boundary condition estimation in a near-scale gas-turbine combustor
… algorithms are employed to recover the acoustic boundary conditions. These techniques are used with a combination of two resources: dynamic pressure measurements obtained during combustor operation, and a finite element method-based model of the combustion chamber. Results of a theoretical …

Computational Investigations of Boundary Condition Effects on Simulations of Thermoacoustic Instabilities
… variables, pressure, velocity and temperature to boundary-condition parameters are directly obtained from the solution to sensitivity equations. Thermoacoustic instability is predicted by the Rayleigh criterion. The sensitivity of the Rayleigh index is computed utilizing the sensitivities of field …

Flow Characteristics, Setting, and Basal Boundary Condition of North Greenland Outlet Glaciers
… In this study, the geometric setting and bed condition is therefore investigated to better understand the flow characteristics and dynamics of high-latitude tidewater glaciers in Greenland. New ice thickness measurements are combined with a novel mass conservation method to reconstruct high …

Thermal Boundary Condition Effects On Local Supercritical CO2 Heat Transfer Trends In Tubes
… heat transfer trends under an array of flow conditions with either a constant wall heat flux, constant wall temperature, or conjugate thermal boundary condition. Less emphasis has been placed on studying local sCO2 heat transfer developments. Tubular sCO2 numerical models that implement …

At the edge: An exploration of the boundary condition between architecture and nature
… City of Cape Town revealed that it is the edge condition which differentiates these spaces as being outside the realm of the normative city. The unravelling of the edge from a state of order to disorder took my research to the historical fortifications of Table Bay and specifically, the …

Optimization for a Sturm--Liouville problem with the spectral parameter in the boundary condition
… (S-L) problem with a spectral parameter in the boundary conditions. While previous work on the subject focused on a somewhat simplified model, we consider a more general S-L problem. We use the calculus of variations approach to determine a set of critical points of a corresponding mass …
