Real gas effects in ORC turbines
… ambient conditions. The isentropic exponent and compressibility factor are commonly used to describe a fluid's gas dynamic behaviour and its diversion form ideal gas conditions. Though, the effects of these parameters on turbine performance are not well known. This thesis discusses a series of …

Kinetic modelling simulation and optimal operation of fluid catalytic cracking of crude oil: Hydrodynamic investigation of riser gas phase compressibility factor, kinetic parameter estimation strategy and optimal yields of propylene, diesel and gasoline in fluid catalytic cracking unit
… with published data. For the first time, a Z-factor correlation analysis was used in the riser simulation to improve the hydrodynamics. It was found that different Z factor correlations predicted different riser operating pressures (90 – 279 kPa) and temperatures as well as the riser products. …

Thermodynamic calculations with TK!Solver
… include temperature, pressure, volume, and compressibility factor. Program RESIDUAL.TK calculates residual and total properties of compounds as a function of temperature and pressure using the Pitzer correlation, van der Waals, or Redlich-Kwong equation of state. The residual and total …

On the Growth Rate of Turbulent Mixing Layers: A New Parametric Model
… function velocity profile, and a function for a compressibility factor was generalized from existing theory on the convective Mach number. The compressible model is supported by a detailed evaluation of the currently accepted models and practices, including error analysis of the convective Mach …

Sensitivity Analysis and Uncertainty Quantification of Plasma Jet Instabilities in the VKI Plasmatron
… in the electric power. Results indicate that the compressibility factor has a dominant influence affecting all instability modes. Furthermore, we identify for each instability mode additional thermodynamic and transport properties that determine its instability features; in particular, it is shown …

Evaluation of the Best Equation of State for Enhanced Oil Recovery Use in Ultra-high Pressure Hydraulic Calculation
… and density are shown to be related to the compressibility factor, this study adopted Aspen HYSYS as the simulation tool to evaluate all four EsOS. The predicted compressibility factors (Z) from the different EsOS were compared to experimental data obtained from a wide variety of sources. …

A semi-empirical approach to modelling well deliverability in gas condensate reservoirs.
… correlations include; condensate hybrid compressibility factor, viscosity, density, compositional pseudo-pressure, and dynamic three phase relative permeability. The study made use of published data bases of experimentally measured gas condensate PVT properties and three phase relative …
