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....
An approximate model for base-stock-controlled assembly systems
Avşar, Zeynep Müge; RODOPLU, Umut (Informa UK Limited, 2009-03-01)
This study is on continuously reviewed base-stock-con trolled assembly systems with Poisson demand arrivals and exponential single-server facilities used for manufacturing and assembly operations. A partially aggregated but exact queueing model is developed and approximated assuming that the state-dependent transition rates arising as a result of the partial aggregation are constant. It is shown that the steady-state probability distribution of this approximate model is a product-form distribution for the s...
Assessment of flow and heat transfer characteristics for proposed solid density distributions in dilute laminar slurry upflows through a concentric annulus
Eraslan, Ahmet Nedim (Elsevier BV, 2003-09-01)
A computational model is developed to predict the hydrodynamic and heat transfer characteristics of dilute liquid-solid laminar upflows through a concentric annulus. The dilute slurry is treated as a single phase Newtonian fluid of locally variable physical and thermal properties. Available experimental data of radial solid density distributions in dilute water-feldspar annular upflows is used in the model. Various important characteristics of laminar slurry flows were successfully predicted. It was also sh...

Enhancement of biodegradability by continuous ozonation in Acid Red-151 solutions and kinetic modeling
Gokcen, F; Ozbelge, TA (Elsevier BV, 2005-11-15)
In this work, continuous ozonation of aqueous Acid Red-151 was performed in a stirred tank reactor at neutral pH and 25 degrees C. The results show that ozonation is capable of a rapid conversion of the Acid Red-151 dye molecule to more biodegradable intermediates up to the ozonation time of 120 min at which the optimum BOD5/COD ratio is obtained. The peak BOD5/COD ratios were found to be in the range of 0.028-0.35 for the initial dye concentrations being in the range of 1000-100 mg/L, respectively.
