Simple prediction method of unstable fluid force in turbine blade row of steam turbine

Nihon Kikai Gakkai ronbunshu, 2016
Unstable fluid force may be induced by rotor blade eccentricity in turbo machinery such as steam turbines. To develop a prediction method for unstable fluid force in turbine blade rows, we calculated the fluid force by using computational fluid dynamics (

Investigations on static and dynamic properties of liquid annular seals by a new transient numerical method with circular whirl model [PDF]

AIP Advances
Annular seals are employed in centrifugal pumps to inhibit leakage for reducing the effect of leaking fluid on the main flow. However, the seals generate fluid excitation forces while controlling the leakage flow, which seriously compromises the ...

Effect of Temperature and Atmosphere on Agglomeration of Bed Particles in a Bubbling Fluidised Bed Burning Na‐Enriched Coal

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Agglomeration of bed materials during circulating fluidised bed (CFB) combustion or gasification of high‐alkali fuel is a practical challenge in industrial practice. This work investigates experimentally the effect of temperatures (700°C–900°C) and atmosphere (air equivalence ratios 1.61–0.53) on agglomeration in a lab‐scale bubbling fluidised

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...
