A simple, virial-like cubic equation of state has been developed from the general form of the perturbed hard core model. The equation simultaneously incorporates saturation liquid volume and saturation pressure information for pure compounds. With two adjustable parameters per binary, it can represent low-pressure vapor—liquid equilibria as well or better than dual methods. This model applies a single equation to both phases and necessitates only a fraction of the input information required by dual methods. The results indicate that the cubic equations do not necessarily need a van der Waals type hardcore term in order to successfully predict the phase equilibrium.

An empirical method for the second viral coefficients of non-standard fluids
Kis, Konrad; Orbey, Hasan (Elsevier BV, 1989-9)
A new empirical method is proposed for the extension of Pitzer-Curl type correlations of the second virial coefficient to non-standard fluids as define
AN EMPIRICAL VIRIAL-LIKE CUBIC EQUATION OF STATE FOR PHASE EQUILIBRIUM CALCULATIONS
Orbey, H; Orbey, N (Informa UK Limited, 1990-4)
An empirical cubic equation of state(EOS) was obtained by truncating the virial expansion in reciprocal of molar volume after the third term. The constants of the EOS was generalized in terms of critical temperature, critical pressure and Pitzer's acentric factor. In pure component applications the EOS exhibited a performance comparable to Peng-Robinson (1976) EOS in the reduced temperature range of 0.5 to 1. The present EOS tends to predict better saturation liquid volumes at reduced temperatures below 0....
Mathematical modeling of fluidized bed combustors with radiation model
Alagöz, Düriye Ece; Selçuk, Nevin; Department of Chemical Engineering (2006)
Simultaneous solution of the conservation equations for energy and chemical species in conjunction with radiative transfer equation was carried out by coupling a previously developed and tested system model of fluidized bed combustion (FBC) to an existing radiation model. The predictive accuracy of the coupled code was assessed by applying it to 0.3 MWt METU Atmospheric Bubbling Fluidized Bed Combustor (ABFBC) Test Rig burning lignite in its own ash and comparing its predictions with the measured temperatur...
The method of lines solution of discrete ordinates method for Nongray media experimental
Çayan, Fatma Nihan; Selçuk, Nevin; Department of Chemical Engineering (2006)
A radiation code based on method of lines (MOL) solution of discrete ordinates method (DOM) for the prediction of radiative heat transfer in nongray absorbing-emitting media was developed by incorporation of two different gas spectral radiative property models, namely wide band correlated-k (WBCK) and spectral line-based weighted sum of gray gases (SLW) models. Predictive accuracy and computational efficiency of the developed code were assessed by applying it to the predictions of source term distributions ...
Generalized coutte flow of herschel-bulkley fluid through eccentric annulus-an approximate solution
Seyidoğlu, Tijen; Tosun, İsmail; Department of Chemical Engineering (2006)
Generalized Couette flow of a Herschel-Bulkley fluid in an eccentric annulus is analyzed by approximating the flow geometry as a slit of variable height. Besides an imposed pressure gradient, one of the plates is considered non-stationary to take into account the axial and/or angular motion of the inner pipe in an eccentric annulus system. Depending on the magnitude and the direction of the applied pressure gradient with respect to the plate velocity, three separate flow cases are studied in which the veloc...
