Added Value of CESM‐Driven WRF for Mean and Extreme Precipitation Over Complex Terrain in Southwest Asia

International Journal of Climatology, EarlyView.
Southwest Asia remains understudied in high‐resolution regional climate modelling despite its climatic sensitivity and complex orography. We compare WRF (10 km), CESM (~2°), and ERA5 (0.25°) for 1950–2002, with supplementary validation against CHIRPS and PERSIANN‐CDR. WRF corrects the unrealistic summer precipitation overestimation of CESM and improves

Rheology based CFD modeling of magnetite medium segregation in a dense medium cyclone

, 2015
In this work, an improved multiphase computational fluid dynamics (CFD) model is developed for simulating medium segregation in a dense medium cyclone. This model approach uses the modified Mixture model with the granular option and Reynolds stress model

Spatio‐Temporal Assessment of the Complementarity Between Hydroelectric, Wind and Solar Energy Sources for Northeastern Brazil

International Journal of Climatology, EarlyView.
Using 24 years of climate and hydrological data, this study quantifies the spatiotemporal complementarity among the water availability of the Sobradinho reservoir, wind and solar in Northeastern Brazil. The integration of hierarchical clustering and compromise programming reveals how seasonal variability and reservoir dynamics interact with atmospheric

A comprehensive CFD model of dense medium cyclone performance

, 2007
A computational fluid dynamics (CFD) model of the dense medium cyclone (DMC) has been developed, using Fluent, by coupling component models for the air-core, the magnetite medium and coal particles.

How Thunderstorms Are Changing in Mexico: Trends and Characteristics

International Journal of Climatology, EarlyView.
Thunderstorm days in Mexico have increased significantly since 1992, with pronounced regional and seasonal contrasts. Increasing moisture emerges as the most spatially coherent environmental signal. At the same time, enhanced instability characterizes northeastern and central Mexico, revealing distinct regional controls on thunderstorm activity and ...

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

A plant comparision of the vorsyl separator and dense medium cyclone in the treatment of Indian coals.

, 2003
In India, a major portion of metallurgical coal of desirable ash is produced from the dense medium cyclone (DMC) process. Based on detailed laboratory studies, vorsyl separator (VS), a centrifugal dense medium separator, was established to be a possible ...

A wavelet‐based method for the assessment of hydrodynamic model behavior against observed sea level variability

Limnology and Oceanography: Methods, EarlyView.
Abstract Sea level outputs from hydrodynamic models are often assessed against tide gauge data by comparing the standard deviations of modeled and observed time series, and by calculating the Pearson correlation coefficient and centered root mean square error (cRMSE) between the two.

Modelling the Multiphase Flow in Dense Medium Cyclones

The Journal of Computational Multiphase Flows, 2010
Dense medium cyclone (DMC) is widely used in mineral industry to separate solids by density. It is simple in design but the flow pattern within it is complex due to the size and density distributions of the feed and process medium solids, and the turbulent vortex formed.
