... heating inside the seal clearance has not been indicated completely. Therefore, the leakage and windage heating of staggered labyrinth seals with smooth and honeycomb lands were experimentally and numerically studied. The large-scale and multifunctional sealing test rig were employed to carry out...

... of fluid (m/s) V φ = tangential velocity (m/s) x = axial coordinate (m) α = tooth front inclined angle (deg) Δ T = windage heating (K) θ = tooth rear inclined angle (deg) λ t = turbulent flow parameter π = pressure ratio ω...

...) The temperature rise of a rotating adiabatic disk surface due to windage heating can be measured by the infrared measurement method with the theory of adiabatic disk temperature. The tangential velocity difference between the rotor and the rotating core which is usually represented by the swirl ratio, is the key...

...Xin Yan; Jun Li; Zhenping Feng Three-dimensional Reynolds-averaged Navier–Stokes solutions are employed to investigate the discharge and total temperature increase characteristics of the stepped labyrinth seal with honeycomb land. First, the relations between the windage heating number...
