“…V dr i was determined using Eq. (8). The frictional losses are determined according to Geankopolis [14] where L p and D p are the plate thickness (which sets the fluid path length along the distributor in this configuration) and the distributor diameter.…”

Comparison of CFD and one-dimensional Bernoulli solutions of the flow in a plate and frame ultrafiltration module in Z configuration AbstractPredictions of flow and pressure distributions in one bank of a plate and frame ultrafiltration module with five channels in parallel operating in a Z configuration were predicted using (1) Bernoulli's equation and a momentum balance in one dimension and (2) a threedimensional field solution (Computational Fluid Dynamics) of the Navier-Stokes equation. CFD solutions were taken as the benchmark and used to refine the 1D model being developed to evaluate flow and pressure distributions for different operating conditions and ultimately different module configurations. The 1D model was able to provide quantitatively accurate flow distribution and qualitatively representative pressure distributions. Flow distributions increased monotonically with increasing channel number, maximum/minimum flow ratios in channels increased from 2 to 6.9 with oil (µ = 0.0361 kg/m/s) as the design cross flow velocity increased from 0.5 to 5 m/s. Pressure distributions were well predicted qualitatively but were typically 40% lower than the CFD solution in the distributor. Key to the accuracy of the 1D model were the implementation of (a) variable contraction co-efficients in the distributor orifice, (b) the 1/7th power law for velocity profiles in the plenums (c) a new approach for combining flows in the collector and (d) assuming only one half of the orifice area was being effectively used by the fluid.

“…This approach has been used to model the circulatory system of the human body, where, for example, a capacitor was used to represent the elasticity of the blood vessels [5,6]. Toldy et al [7] and Ke and Ti [8] used a similar approach to model pipeline flow.…”

“…The different equations are used depending on the working pressure of the network and the assumptions made with regard to the conditions of the network operation (Osiadacz, 1987;Osiadacz, 2001;Kralik et al, 1988). Three equations describing the gas flow through a pipeline network are derived from the equation of continuity, the equation of motion and the equation of energy (Osiadacz & Chaczykowski, 2001;Ke & Ti, 2000):…”

Electric power generation relies increasingly on the natural gas supply system as additional natural gas‐fired power plants are installed in restructured power systems. In this context, the economics and the reliability of electric power and natural gas systems will impact one another. This article addresses the interdependency of electricity and natural gas systems and summarizes approaches for the interdisciplinary operation and the scheduling of the coupled energy systems. This article starts from an introduction of basic knowledge for the electric power system and the natural gas system. The survey will be given for the research in the past about the interdependency of natural gas and electric power system. This article presents two integrated short‐term scheduling models. The first one is from the viewpoint of the independent system operator (ISO), which proposes a security‐based methodology for the unit commitment solution when considering the natural gas transmission system and contracts. The second integrated model considers a joint operator for the coordinated scheduling of the interdependent power and natural gas systems. The integrated operator uses a Lagrangian relaxation (LR)–based model for the coordinated least‐cost allocation of natural gas resources to individual gas loads and power plants.
