... solutions. This paper presents an integrated study of the dynamic performance and fatigue-life characteristics of the optimized Savonius-rotor VAWT composite blades. Furthermore, this paper introduces an experimental validation, numerical modeling, and visualization/verification study of the optimized VAWT...

...S. Gil; J. Deferrari We present a model intended to predict mainly the residential and commercial natural gas consumption in urban areas, for the short and intermediate ranges of time. In the short range, the model has been successfully used to forecast the daily gas consumption of major cities...

...Shankar Earni; Shoubo Wang; Ram S. Mohan; Ovadia Shoham; Jack D. Marrelli Current design and performance of the GLCC © 1 separator is dependent on the prediction of the upstream inlet flow conditions based on available models. It is expected that early detection of terrain slugging (slug length...

...Nevin Selc¸uk; Engin Degirmenci; Yusuf Gogebakan A comprehensive model for continuous combustion of lignite with wide size distribution burning in its own ash in an atmospheric bubbling fluidized bed combustor (ABFBC) has been presented and used to correlate the data from a 0.3 MW ABFBC test rig...

...Jakub Siemek; Jerzy Stopa In this paper, a mathematical model and numerical investigations on dynamic water/oil contact (WOC) in a reservoir with active bottom waters are addressed. An original analytical solution describing the theoretical shape of the dynamic oil-water contact in the reservoir...

... and their analysis becomes a problem. The paper presents mathematical models of the pressure-volume behavior for two different possible failures around the casing shoe, annular crack (cement-rock parting) and formation fracture. The study submits that these two failure modes would control abnormal LOT patterns...

...Turhan Yildiz This study presents a simplified method to predict inflow performance of and cumulative production from selectively perforated wells in bounded reservoirs. The model first calculates the pseudo-skin for a fully perforated well penetrating a formation with only unit thickness...

...-riser systems, such operations cause even more severe change in flow conditions. A two-fluid model has been developed to determine the transient behavior of fluids during these operations. A one-dimensional set of equations for bubble/mist, annular and stratified flows has been derived. Slug flows were...

... knowledge on the mechanism of formation and destruction ongoing in fluidized beds has to be obtained. In this work, a detailed chemistry model is combined with a two-phase model for a stationary fluidized bed to calculate the emissions of a single fuel particle in a laboratory-scale stationary fluidized bed...

... of constraints, while the convergence of GNASA is limited. These codes have been applied in nonequilibrium evolution process of hydrogen-oxygen mixture. The nonequilibrium process has been modeled by using only two constraints in addition to elemental constraints. The results are in good agreement with detailed...

.... The total pressure drop was reduced by over 45-fold. The frictional pressure drop model proposed includes both irreversible and buoyancy terms. The model was adjusted to fit our data and shows excellent agreement with laboratory data available. Contributed by the Petroleum Division and presented...

...Michael A. Adewumi; E. S. Eltohami; W. H. Ahmed The modeling of pressure transient across constrictions is achieved by using a one-dimensional, isothermal, noncompositional, single-phase representation of the Eulerian model. A TVD scheme was used to solve the ensuing nonhomogeneous hyperbolic set...
