Brush seal with thermo-regulating bimetal elements

Temperature Insensitive Curved Bimetal Elements

Space structures are subjected to appreciable temperature variations when they enter and leave direct solar radiation zones. These variations cause thermal strains and related structural distortions. Such deformations are often a nuisance and much engineering e ort, such as active control methods, is currently being invested in reducing the deformations and alleviating their e ects. This paper ...

Thermo-responsive brush copolymers with structure-tunable LCST and switchable surface wettability

Thermo-responsive brush copolymers poly(methyl methacrylate (MMA)-co-2-(2-bromoisobutyryloxy) ethyl methacrylate (BIEM)-graft-(N-isopropyl-acrylamide) (NIPAAm)) were synthesized using Cumediated “living” radical polymerization (LRP) approach. Varied grafting densities of the brushes were obtained through adjusting backbone structure as random, gradient and block respectively. The effect of graf...

Effect of a ring type barrier and rotational speed on leakage flow of gas turbine brush seal

This paper investigates the effect of inserting a ring type barrier on leakage flow of brush seals with different bristles clearances (the distance between bristle pack tip and rotor surface). The ring is placed on both upstream and downstream sides of the bristles. An axisymmetric CFD model is employed to calculate radial pressure distribution along backing plate, axial pressure variation on r...
