Entrance and exit region friction factor models for annular seal analysis
(1988)
The Mach number definition and boundary conditions in Nelson's nominally-centered, annular gas seal analysis are revised. A method is described for determining the wall shear stress characteristics of an annular gas seal ...
Finite control volume modeling of the turbulent motion of air in an enclosure
(1987)
The FCVM has been used to solve both open flow problems and turbulent flow problems. The particular problems chosen for consideration were the flow between infinite parallel plates and the buoyant flow in a square enclosure. ...
Extensions of the control volume based finite element method for fluid flow problems
(1987)
The Control Volume Based Finite Element Method (CVFEM) has been extended in two main aspects. The first is the integration of the vorticity-streamfunction formulation with the CVFEM. The key contribution of this work is ...
Study of air infiltration energy consumption
(1992)
The influence of heat recovery on the energy impact of air infiltration, and the systematic error due to the steady-state method were studied both experimentally and theoretically. Two methodologies suitable for measurement ...
A generalized methodology for manufacturability evaluation
(1993)
In a design for manufacturing (DFM) approach the designer has to consider the interactions between the various parameters in the design and the ease with which it can be manufactured, very early in the design process. This ...
Particle lift force and particle behavior in suspension flows
(1994)
In this study, particle lift force and its influence on particle behavior are considered in suspension flows. Saffman force, a particle lift force derived in parallel laminar shear flow, is extended to a general particle ...
A methodology to measure retrofit energy savings in commercial buildings
(1993)
Measured energy savings promote and sustain energy conservation retrofits by verifying the success of retrofits, determining pay-back schedules, guiding the selection of future retrofits and identifying opportunities for ...
Radial Jet Reattachment Combustion
(1993)
A novel combustion nozzle utilizing flame impingement has been developed from the concept of Radial Jet Reattachment. The RJR concept was emulated because of its high turbulence intensity and enhanced transport properties, ...
Energy considerations in active vibratory systems
(1994)
Active vibration isolation systems can generally offer substantial improvements in dynamic performance. However, their use has been limited due to the burden of cost of their implementation and operation. The cost of ...
Freeze/thaw characteristics of room temperature heat pipes-incorporating thermal history effects and non-condensible gas charging
(1993)
The freeze/thaw characteristics of room temperature heat pipes have been investigated experimentally and analytically to determine the effects of non-condensible gas loading and thermal history. Experimentally, the freeze/thaw ...
