Experimental analysis of flashing front propagation in superheated water—Effects of degree of superheat, tube inclination, and secondary nucleation

Physics of Fluids, 2020
A comprehensive experimental investigation on free surface flashing and flashing front (FF) propagation after sudden depressurization of stagnant water is reported. Elaborate high-speed imaging and some limited pressure and temperature recording have been made using two experimental facilities. A new rupture mechanism has been developed, which offers a

Evaluation of the State for the Material of the Live Steam Superheater Pipe Coils of V Degree

Advanced Materials Research, 2014
The main aim of the undertaken research was to evaluate the state of the material of V degree live steam superheater pipe coils made of 10CrMo9-10 (10H2M) chromium-molybdenum steel as well as to determine their usability for further operation. The pipe coils came from a steam boiler working at a power plant.

A STUDY ON THE SPRAY–WALL INTERACTION MODEL CONSIDERING DEGREE OF SUPERHEAT IN THE WALL SURFACE

Numerical Heat Transfer, Part B: Fundamentals, 2001
In this study, a new concept is proposed in order to simulate the behavior of a multi-component fuel spray impinging on a hot surface. The distillation curve of the fuel is considered so as to describe the vaporization property of each component in the gas oil, since the superheating degree of the surface, defined by the temperature difference between ...

The effect of the inlet steam superheat degree on the non-equilibrium condensation in steam turbine cascade

Physics of Fluids
Due to the high steam velocity and low thermal parameters at the turbine's final stage, steam generates non-equilibrium condensation and forms a large number of small droplets during the process of pressure expansion. The wet steam mixed with droplets impinges on the turbine blades, endangering turbine operation safety and reducing turbine work ...

A comprehensive investigation and optimization of superheat degree on performance of supersonic nozzle by considering non-equilibrium condensation and entropy generation analysis

Physics of Fluids
Non-equilibrium condensation (NQC) induced heat transfer in the supersonic nozzle (SSN) results in entropy production and alters the flow structure. The analysis of entropy production offers valuable insights for enhancing the design of industrial equipment by pinpointing the origins of energy losses.
