An experimental and numerical model of a solar chimney was proposed in order to predict its performance under varying geometrical features in Iraqi environmental conditions. Steady, two dimensional, turbulent flow was developed by natural convection inside an inclined solar chimney. This flow...

Pelton turbine (or Pelton wheel) is among the most efficient impulse turbines and has retained its existence in hydropower for well over a century. However unlike in the development of the reaction turbines, where Computational Fluid Dynamics (CFD) have been successfully applied for more than 20...

In a tangentially coal-fired boiler, for locations inside and near the combustor, heat-transfer by radiation is significant, and hence, ash particles arrive in molten state. The aim of the present study is to adopt a mechanistic modeling approach which incorporates energy-conservation principles...

The performance of individual wind turbines is crucial for maximum energy yield, however, their performance is often reduced when turbines are placed together in an array. The wake produced by the rotors interacts with downstream turbines, resulting in a reduction in power output. In this paper,...

A numerical technique that employs a computational fluid dynamics (CFD) code is used to perform coupled fluid–structure interaction simulation of a wave energy device in order to assess power output in a 3D numerical wave flume. The current method determines the motion of the buoy from the...

In this paper, the energy performance comparison of single glass, double glass and a-Si semi-transparent PV module integrated on the Trombe wall façade of a model test room built in Izmir, Turkey has been carried out. The system has been operated during the days February 25–26th. The...

The main objective of this paper is to evaluate the fuel/oxidant gas distributions as well as thermal stresses of an anode-supported solid oxide fuel cell (SOFC) test cell under different operating conditions. In this study, the commercial computational fluid dynamics (CFD) code Star-CD with...

Many computational fluid dynamics polymer-electrolyte-membrane fuel cell models have been presented over the last few decades. A detailed literature overview of models, ranging from one-dimensional, single-component to complete three-dimensional, large-scale setups, is presented with an emphasis...

A HFPE (hydraulic free-piston engine) has been proposed by the SKLE (State Key Library of Engines) in Tianjin University as a mean to significantly improving the IC (Internal Combustion) engines' cycle thermal efficiency and lowering exhaust emissions. As the piston dynamic and the cylinder...

The numerical study of laminar forced convection inside double-flow solar air heater with electrohydrodynamic technique is investigated by finite difference method. The electric field is generated by the wire electrodes charged with DC high voltage. The mathematical modeling of computational...
