... momentum losses. Correspondingly, the three-dimensional fluid models were able to capture boundary layer losses affected by 3D geometries. The fundamental FSI equations may be presented in terms of energy conservation, where the overall energy of the system is conserved and essentially consists...

.... A two-dimensional (2D) transient axisymmetric heat and mass transfer model was developed through the use of a lumped-parameter boundary-layer model to simulate the inlet flow and determine the time-dependent inlet duct heat transfer. This model was validated with transient 2D computational fluid...

... boundary layer model of turbine efficiency. An analytical model is developed for a viscous flow turbine. This is compared to experimental measurements of the efficiency of a Tesla turbine using compressed air. The semiempirical scaling law predicts that below a rotor diameter of between about 11 mm and 4...

... shock events contributed to abrupt, localized heat transfer enhancements, the influence of NGV wake segments on the boundary layer could not be discounted when duration of unsteadiness was considered. References Dunn , M. G. , 2001...

... modified, following recommendations of earlier CFD work (Final Report No. TT03R01, 2003), to produce a secondary flow/wake structure that allows the prediffuser to operate at a higher area ratio without boundary layer separation. This is demonstrated to increase static pressure recovery and reduce dump...

...Masayoshi Shimo; James V. Canino; Stephen D. Heister Oil flow behavior within a lubrication system utilized in a turbofan engine has been studied using a two-dimensional model for a seal runner and a sump wall. A two-dimensional, axisymmetric boundary layer method is utilized to derive a model...

...F. Malpica; N. Moreno; A. Tremante This study presents the analysis of the thermal boundary layer considering combined convection and radiation in an absorbing, emitting, and scattering medium flowing over a flat plate. At high temperatures the presence of thermal radiation alters the temperature...
