Modeling Unsteady Compressible Flow



Introduction
In this tutorial, FLUENT's coupled implicit solver is used to predict the time-dependent

ow through a two-dimensional nozzle. As an initial condition for the transient problem,
a steady-state solution is generated to provide the initial values for the mass
ow rate at
the nozzle exit.

Prerequisites
This tutorial assumes that you are familiar with the menu structure in FLUENT and that
you hav ....etc

ARM is a 32-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by ARM Holdings. It was known as the Advanced RISC Machine, and before that as the Acorn RISC Machine.The relative simplicity of ARM processors made them suitable for low power applications. This has made them dominant in the mobile and embedded electronics market as relatively low cost and small microprocessors and microcontrollers.

Numerical Modeling of Cross Flow Compact Heat Exchanger
with Louvered Fins using Thermal Resistance Concept


INTRODUCTION
As the engine power density continuously increases and
additional heat sources such as intercooler for boosted
intake air charge, HVAC system, oil cooler and EGR
cooler, are commonly used, thermal loads to the vehicle
thermal management system have been significantly
increased. On the other hand, the engine room is more
crowded than ever in orde ....etc

Abstract
To numerically simulate aerodynamics of rotor-airframe interaction in a
rigorous manner, we need to solve the Navier-Stokes system for a rotor-airframe
combination as a whole. This often imposes a serious computational burden since
rotating blades and a stationary body have to be simultaneously dealt with. An efficient
alternative is to adopt a momentum source method in which the action of rotor is
approximated as momentum source over a rotor disc plane in a stationary
computational domain. This makes the simulation much ....etc

Abstract
In this paper steady-state modeling of Static VAR Compensator (SVC) and Thyristor Controlled Series Compensator (TCSC) for power flow studies has been represented and discussed in details. Firing angle model for SVC was proposed to control the voltage at which it is connected. In same manner firing angle model for TCSC is used to control active power flow of the line to which TCSC is installed. The proposed models take firing angle as state variable in power flow formulation. To validate the effectiveness of the proposed mode ....etc

Usefulness of DC Power Flow for Active Power Flow Analysis



I. INTRODUCTION
STATIC power system analysis has always been
performed using full power flow. It is one of the
fundamental tools for power system analysis and is used in
the operational as well as planning stages. Vertically
integrated companies have used it to control their systems, as
well as to plan the optimal economic operation of generation
resources, either by means of optimal power flo ....etc
