The objective of this work is to develop deep theoretical methods that are based on the solution of the integral boundary layer equations for investigating film cooling in liquid rocket engine. The integral model assumes that heat is transferred from hot free stream gas to the liquid film both by convection and radiation. The mass is transferred to the free srteam gas by the well-known blowing ...

Results are presented of simulations of a stable boundary layer of moderate surface condition and zero overlying inversion strength. The layer depth is matched to model scale by artificially thickening the boundary layer by means of flow generators (‘spires’) at the working-section inlet. A non-uniform inlet temperature profile is essential in order to preclude the upper part of the layer retai...

Cementing systems using ultra-lightweight hollow spheres can improve lightweight cement performance in deepwater operations and provide a viable alternative to conventional lightweight cement slurries. Efforts to expand the temperature limits of MWD and LWD tools have seen limited success. New approaches may be necessary if industry is to meet the demand for gas from deep reservoirs. Mixing fra...

Deconstruction is a powerful means to explore the rich dynamics of gauge theories in four and higher dimensions. We demonstrate that gauge symmetry breaking in a compactified higher dimensional theory can be formulated via deconstructed 4D moose theory with spontaneous symmetry breaking and without boundary condition. The proper higher-D boundary conditions are automatically induced in the cont...
