Validation of drift and diffusion coefficients from experimental data

Journal of Statistical Mechanics: Theory and Experiment, 2010
Many fluctuation phenomena, in physics and other fields, can be modeled by Fokker–Planck or stochastic differential equations whose coefficients, associated with drift and diffusion components, may be estimated directly from the observed time series. Its correct characterization is crucial to determine the system quantifiers. However, due to the finite

REGIONS OF VALIDITY OF VARIOUS ABSORPTION-COEFFICIENT APPROXIMATIONS

Journal of Meteorology, 1953
Abstract Elsasser's integral for the absorption by a periodic line pattern is evaluated and used to examine the validity of various approximations concerning the absorption coefficient. It is found that composite absorption curves, obtained by ignoring overlapping for small optical paths and ignoring the pressure-dependent term in the denominator of ...

CFD Validation of Incompressible Cross-Flow Discharge Coefficients

NAFEMS International Journal of CFD Case Studies, 2000
Validation against air systems problems is required to enable Computational Fluid Dynamics (CFD) codes to be confidently used in the design of turbine cooling air systems. CFD calculations of orifice cross-flow discharge coefficients (Cd) have been compared with measurements by Rohde et al [1].
