The Double is a novella written by the Russian writer Fyodor Dostoevsky. It tells the tragic but comic tale of the polite and well-established titular councilor Yakov Petrovitch Golyadkin. His problems begin when his exact double enters his life and begins to take over. The Chaotic Motion of a Double Pendulum Carl W. Akerlof Septem The following notes describe the kinematics of the double pendulum. The starting point is a pendulum consisting of two point masses, m, and m2, suspended by massless wires of length l1 File Size: KB.

Accidental double-diffusive mixing 1 Reply When setting up the stratification for the Nansen “dead water” demo (that we’ll show later today, and until then I am not allowed to share any videos, sorry!), I went into a meeting after filling in layer 4 (the then lowest). A series of large-scale numerical simulations is presented, which incorporate parameterizations of vertical mixing of temperature and salinity by double-diffusion and by small-scale turbulence. These simulations reveal the tendency of double-diffusion to constrain diapycnal volume transport, both upward and downward. For comparable values of mixing coefficients, the average diapycnal velocity Author: Timour Radko, Erick Edwards.

[N E Bixler; E Speigel; American Society of Mechanical Engineers. Fluids Engineering Division.;]. The double-diffusion mixing lowers the potential energy of the system. This potential energy is converted into kinetic energy within the convecting layers.
In addition, the convecting layers allow a large flux of momentum from the salt-fingering interface to the double-diffusive interface. book review. Double Diffusive Convection Article (PDF Available) in Oceanography (Washington D.C.) 28(1) March with 80 Reads. DOUBLE-DIFFUSIVE PHENOMENA x J.
Turner University of Cambridge, Cambridge, England INTRODUCTION The study of convective motions produced by unstable density distributions in a fluid is now highly developed.
Most attention has been given to the case of a thin horizontal layer of fluid, heated below and cooled above, and results obtained using.

We consider double diffusive convection in a viscoelastic fluid of Oldroyd-B type with weak-electrical conductivity occupying a horizontal channel of infinite extent and depth d.A Cartesian coordinate system is taken with the lower surface in the xy-plane and z-axis is chosen vertically upwards.A uniform adverse temperature gradient ΔT and a stabilizing concentration gradient ΔS are Cited by: Research on convective-diffusive fluid motions in porous media has a notable relevance (increasing with the number of salts dissolved in the fluid) either for geophysical applications (engineering Author: Salvatore Rionero.
mixing. The diapycnal double-diffusive fluxes could drive lateral interleaving motions, and hence lateral fluxes of salt and heat. This early work, and much more, is described in a clear and physical manner in Turner (); it is highly recommended reading. Most of the world ocean has strong double-diffusive potential somewhere in the water.
Double-diffusive convection is a mixing process driven by the interaction of two fluid components which diffuse at different rates. Leading expert Timour Radko presents the first systematic overview of the classical theory of double-diffusive convection in a coherent narrative, bringing together the disparate literature in this developing by: Double-diffusive convection occurs in many natural flows with fluid density determined by two scalar components, such as the thermohaline convection in the ocean.
It plays a crucial role in mixing and scalar transport. Here we report a systematic study of such flow under a destabilizing salinity gradient and a stabilizing temperature by: Geophysical Monograph Series This series publishes monographic works and compilations of papers on a single topic, spanning all scientific areas in the Earth and space sciences, and frequently focusing on multidisciplinary issues.

Connect with me:  Double‐diffusive convection caused by variations in solute concentration and temperature within a fluid body has previously been studied in connection with oceanic mixing processes, astrophysics, metallurgy, geology, and vadose zone hydrology but has not previously been studied in connection with thermohaline transport in a groundwater well.
This paper considers whether double Cited by: Double-and multi-diffusive phenomena occur in fluids containing more than one component contributing to their density (e.g. salt and heat), and exhibit unusually beautiful patterns.

I made the following changes. Double-diffusive convection (DDC), where the flow density depends on two scalar components, is of great relevance in many natural phenomena and engineering applications, such as oceanography (1 –3), geophysics (4, 5), astrophysics (6 –10), and process technology ().A comprehensive review of the field can be found in the recent book of ref.
In DDC flows the two Cited by: The Double is the most Gogolesque of Dostoevsky's works; its subtitle "A Petersburg Poem" echoes that of Gogol's Dead Souls. Vladimir Nabokov called it a parody of "The Overcoat".
Many others have emphasized the relationship between The Double and other of Gogol's Petersburg Tales. One contemporary critic, Konstantin Aksakov, remarked that. DOUBLE-DIFFUSIVE CONVECTION Double-diffusive convection is a mixing process driven by the interaction of two ﬂuid components that diffuse at different rates.
This phenomenon has important ramiﬁcations in oceanography and in numerous other ﬁelds, from crystal growth to magma chambers and stellar interiors.
Nevertheless, several aspects of. force for many studies in double-diffusive or multi-component convection has largely physical applications. More recently, Reena and Rana (b) have studied the thermosolutal convection of micropolar fluids in porous medium in the presence of rotation.
They found the stability effect of rotation in the presence of salinity. Double Feature (Trading Faces Book 4) is awesome Julia DeVillers and Jennifer Roy are awesome writers. I pray &hope they make another Trading Faces Book.
I would totally read it, if my dad or mom will let me get it on my kindle/5(62).Access to this book provides the broad perspective that both young and mature researchers entering these areas should possess, and the book would serve well also in graduate courses in astrophysical and geophysical fluid dynamics this is a lovely book that does justice to a double-diffusive system of very considerable interest.'.Double-diffusive convection is an important fluid dynamic phenomenon that involves motions driven by two different density gradients diffusing at different rates (Mojtabi and Charrier-Mojtabi).
A common example of double diffusive convection is seen in oceanography, where heat and salt concentrations exist with different gradients and diffuse Cited by:
