NUMERICAL CALCULATION OF THE STEAM CONDENSING FLOW

TASK Quarterly, 2001
Considering the flow in the last stages of LP (low pressure) steam turbine the strong non-linearity of the thermal parameters of state and possibility of the two-phase flow have to be taken into account in the numerical calculation of the flow field. In

Re-recognition of the ideal gas and real gas

, 2023
Ideal gas is the most fundamental and simple system in thermodynamics, which has extensive applications in energy research and engineering. By reviewing the physical concept of ideal gas, it is found that the current understanding of ideal gas is still inappropriate and ambiguous, making it challenging to reveal the essential difference between ideal ...

Self-mixing interference effects in tunable diode laser absorption spectroscopy [PDF]

, 2009
We report the effects of self-mixing interference on gas detection using tunable diode laser spectroscopy. For very weak feedback, the laser diode output intensity gains a sinusoidal modulation analogous to that caused by low finesse etalons in the ...
