Contributions of biologists to tropical cyclone research may improve by integrating concepts from other disciplines. Employing accumulated cyclone energy into protocols may foster greater integration of ecology and meteorology research. Considering experienced ecosystems as antifragile instead of just resilient may improve cross-referencing among ecological and social scientists. Quantifying ec...

A phytoplankton bloom was observed in the southeastern Arabian Sea after passage of anti-S-type track Tropical cyclone ARB 06 1998, which lasted for 22 days. The dynamic mechanism investigated with high-resolution satellite remote sensing data, reanalysis data and buoy data. results show that double thermocline structure hindered uplift deep nutrients to surface before tropical arrival. During ...

A new multi inner stage (MIS) cyclone was designed to remove the acidic gas and fine particles produced from electronic industry. To characterize gas flow in MIS cyclone, pressure and velocity distribution were calculated by means of CFD program. Also, the flow locus of fine particles and particle removal efficiency were analyzed by Lagrangian method. When outlet pressure condition was –100mmAq...

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...

Cyclone is a polymorphic, type-safe programming language derived from C. The primarydesign goals of Cyclone are to let programmers control data representations and memory man-agement without sacrificing type-safety. In this paper, we focus on the region-based memorymanagement of Cyclone and its static typing discipline. The design incorporates several advance-ments, including su...

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...

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...

Cyclone separators are widely used in a variety of industrial applications. A low-mass loading gas cyclone is characterized by two performance parameters, namely the Euler and Stokes numbers. These parameters are highly sensitive to the geometrical design parameters defining the cyclone. Optimizing the cyclone geometry therefore is a complex problem. Testing a large number of cyclone geometries...

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...
