Texto completo da fonteAt oceanic basin scales, vertical velocities are several orders of magnitude smaller than their horizontal counterparts, rendering a formidable challenge for their direct measurement in the real ocean. Therefore, their estimations need a combination of observation-based datasets and theoretical considerations.Historically, scientists have employed various techniques to estimate vertical velocities across different scales constrained by the available observations of their time. Various approaches have been attempted, ranging from methods utilizing in situ horizontal current divergence to those based on intricate omega-type equations. However, the Sverdrup balance has captured the attention of researchers and ours due to its robust and straightforward description of ocean dynamics. One of the fundamental components of the Sverdrup balance is the linear vorticity balance (LVB: βv = f ∂z w). It introduces a novel vertical dimension to the conventional Sverdrup balance, establishing a connection between vertical movement and the meridional transport above it.In order to advance on the theoretical prospect of estimating the vertical velocities, it is primarily identified the annual and interannual timescales patterns governing the linear vorticity balance within an eddy-permitting OGCM simulation. Initially, this analysis is conducted over the North Atlantic Ocean, and subsequently expanded to encompass the entire global ocean, focusing on larger scales than 5 degrees. The analysis revealed the feasibility of computing a robust vertical velocity field beneath the mixed layer using the LVB approach across large fractions of the water column in the interior regions of tropical and subtropical gyres and within some layers of the subpolar and austral circulation. Departures from the LVB occur in the western boundary currents, strong zonal tropical flows, subpolar gyres and smaller scales due to the nonlinearities, mixing and bathymetry-driven contributions to the vorticity budget.The extensive validity of the LVB description of the global ocean provides a relatively simple foundation for estimating the vertical velocities through the indefinite depth-integrated LVB. Using an OGCM, it has demonstrated that the estimates possess the capability to accurately reproduce the time-mean amplitude and interannual variability of the vertical velocity field within substantial portions of the global ocean when compared to the reference model. Here, we build the DIOLIVE (indefinite Depth-Integrated Observation-based LInear Vorticity Estimates) product by applying the observation-based geostrophic velocities from ARMOR3D into the indefinite depth-integrated LVB formalism, with wind stress data from ERA5 serving as boundary condition at the surface. This product contains vertical velocities spanning the global ocean's thermocline at 5 degrees horizontal resolution and 40 isopycnal levels during the 1993-2018 period.A comparative analysis between the DIOLIVE product and four alternative products, including one OGCM simulation, two reanalyses and an observation-based reconstruction based on the omega equation, is conducted using various metrics assessing the vertical circulation's multidimensional features of the ocean vertical flow. The omega equation-based product displays large departures from the synchronicity and baroclinicity reproduced by the validation ensemble. However, in regions where the LVB holds as a valid assumption, the DIOLIVE product demonstrates a remarkable ability to replicate the baroclinic structure of the ocean, exhibiting satisfactory spatial consistency and notable agreement in terms of temporal variability when compared to the two reanalyses and the OGCM simulation

Abstract Within the processes of fluidized bed combustor and catalyst regenerator, there are recycling part of fly ash and reintroducing into the bed of reactor to improve the efficiency, or being feedback the used catalyst into the bubbling fluidized bed for regeneration. In the feedback processes, the over high velocities in the feedback tube will significantly cause attrition in the bed and result into the elutriation of fine particle, also change the particle size distribution and hydrodynamics of the bed. Experimental work was carried out in a batch gas fluidized bed with 6.62cm inner diameter and 2.5m height and perforated distributor. Operating velocities is controlled between from 1 to 5 Umf (minimum fluidization velocity), and the single nozzle gas velocities are handled from 50m/s to 208m/s with inner diameters of 3,4,4.5, and 5mm individually. The used materials are silica sand that are the average sieve diameters of 195,296, and 421mm respectively. The experimental results show that the attrition is function of particle size distribution, materials nature, single nozzle velocities and superficial gas velocities, the empirical attrition rates have been developed by two models; one is from the energy (model 1), the other is from particle motion (model 2). There are shown as follows: Model 1:Rt=ka0Fr*= ka0(Uor+Us)(U0-Umf)W/(gdp) ka0=7.943×10-10 [1/s] for sand Model 2:Rt=ka0(Uor+Us)(QB/A)W where (QB/A)=r(U0-Umf) ka0=2.597×10-7[s/m2 ] for sand The elutriation rate constant is modified by attrition effect. We define the attrition elutriation constant, Kia*, instead of Ki* for the elutriation dominated by attrition effect. We also modify Geldart (1979) empirical correlation, and develop the empirical elutriation equation as follows for this attrition elutriation system: Kia*/pgU0=7.5 exp[-5.4Ut/U0] for U0>Ut
