The General Circulation of the Tropical Atmosphere and Climate Changes [PDF]
, 2012 I examine the general circulation of the tropical atmosphere and climate changes. First, the response of the zonal surface temperature gradients and zonally asymmetric tropical overturning circulations (Walker circulations) to substantial changes in the ...

Drilling fluid loss model and loss dynamic behavior in fractured formations
Petroleum Exploration and Development, 2014 In view of the lost circulation in fractured formations, a two-dimensional transient model for describing a power-law drilling fluid loss in an arbitrarily-oriented, compressible, permeable, rough-walled fracture was introduced.

Nonlinear dynamics of sand banks and sand waves [PDF]
, 2000 Sand banks and sand waves are two types of sand structures that are commonly observed on an off-shore sea bed. We describe the formation of these features using the equations of the fluid motion coupled with the mass conservation law for the sediment ...

Single-layer Axisymmetric Model for a Hadley Circulation with Parameterized Eddy Momentum Forcing
Journal of Advances in Modeling Earth Systems, 2009 An axisymmetric single-layer model is used to study interactions of the Hadley circulation with extratropical eddies. Eddy momentum fluxes are parameterized using a simple closure motivated by calculations with an idealized dry general circulation model (

Application of Circulation Controlled Blades for Vertical Axis Wind Turbines [PDF]
, 2013 The blades of a vertical axis wind turbine (VAWT) rotor see an inconsistent angle of attack through its rotation. Consequently, VAWT blades generally use symmetrical aerofoils with a lower lift-to-drag ratio than cambered aerofoils tailored to maximise ...

Fluid Dynamic Relationships Involved in Circulation Cleaning
Journal of Dairy Science, 1968 Abstract Removal of milk deposits on metal pipes using only fluid flow, without benefit of detergent materials, was studied. Soil removal rate was linear at flow rates between 4,000 and 30,000 kg/hour, representing Reynolds Numbers of from 85,000 to 600,000, demonstrating that cleaning effectiveness steadily improved as the pumping rate increased.

Effects of Salinity Variability on Recent El Niño Events
Atmosphere, 2019 Ocean salinity variability provides a new way to study the evolution of the the El Niño-Southern Oscillation (ENSO). Comparisons between the salinity variation and related processes responsible for sea surface temperature anomaly (SSTA) were ...

Fluid dynamic similarity of circulating fluidized beds
Powder Technology, 1992 Abstract The effects of scale-up on the fluid dynamics of circulating fluidized beds (CFB) are investigated using a single cold laboratory facility with the ability to recycle fluidization gas mixtures of adjustable density and viscosity. By matching five dimensionless parameters, experiments employing plastic, glass and steel powders achieve fluid ...
