gonu storm was formed in tropical basin of indian ocean early in june 2007. gonu is the strongest tropical cyclone that happened in arabian sea and north indian ocean and moved toward oman sea and persian gulf and bouncing the lands around the area. this tropical cyclone made extensive damages and human and financial causalities to countries of oman, iran, afghanistan, pakistan, and india. in t...

A long-term goal of this research is to improve dynamical prediction of tropical cyclones using ensemble methods for making analyses and forecasts. A second goal is to use the information contained in ensemble analyses and forecasts to improve basic understanding of tropical cyclone dynamics. Finally, a third goal is to use ensemble-based sensitivity analysis to target observations for tropical...

In this study the influence of the exit tube geometry on the overall flow properties of cyclones is investigated using detached eddy simulation. The results for different exit pipe shapes and lengths reveal that under certain conditions the outlet has an upstream effect on the flow behaviour within the cyclone. This can in turn result in poor build-up of swirl in the crucial region of the cyclo...

In order to study the effect of dust outlet geometry on the performance of cyclone separators, the gas-solid flow characteristics in four cyclone separators with different dust outlet geometries (without dustbin, with dustbin, with dipleg and with dustbin plus dipleg) have been computationally simulated. The gas flow fields were simulated with Reynolds Stress Model(RSM).The effect of instantane...

This paper presents the design procedure and implementation results of a nonredundant error correcting scheme based on chaotic dynamics using Altera Cyclone III family FPGA board. The scheme is first designed using MATLAB-Simulink then converted to VHDL codes for implementation purposes using the modern tool “Simulink HDL Coder”. The simulation waveforms have been obtained using ModelSim Altera...

Solar reactors featuring a circulating cyclone flow pattern provide enhanced heat transfer and longer residence time increasing the conversion efficiency. Cyclone flow also works in reducing particle deposition on solar reactor walls and exit, which is particularly an important issue in solar cracking reactors to avoid clogging. This paper focuses on the physics of cyclone formation inside a so...

Modern platform Field Programmable Gate Arrays provide larger gate count with increased performance. This feature allows realization of System On Chip on modern FPGAs. When the number of cores increases, the communication demands between cores also increases in SoCs. Hence, Network On Chip has been proposed, to meet out the challenges between the cores. In this paper, a design of low cost, low ...

Separation of suspended droplets in a fluid flow has been a great concern for scientists and technologists. In the current study, the effect of the surface roughness on flow field and the performance of a gas-oil cyclone is studied numerically. The droplets and the turbulent airflow inside the cyclone are considered to be the discrete and continuous phases respectively. The Reynolds stress mode...

Many Western nations face a critical shortage of skilled professionals in science, technology, engineering and mathematics (STEM). However, despite abundant opportunities, few women prepare themselves for careers in these fields. Several of those concerned with the problem have proposed that new media programming, such as television dramas with women engineers, computer professionals and/or eng...

Climate change enters significantly into and is shown to be a direct determinant of residence and job location change decisions. Understanding of how people’s residence and job location change choice behavior is affected and thus responds to the impacts of climate change is essential for transportation planners and adaptation decision makers. As an addition to the current literature, the main p...
