    Despite the notion that computational fluid dynamics (CFD) models are considered complicated, expensive, time-consuming and difficult to formulate, their implementation offers an advanced prospect to move beyond empirical models, which inherit severe limitations in terms of flexibility, scale-up, and optimization of slurry bubble column reactors (SBCRs).Cited by: 2.

The nature of magnetohydrodynamic waves in structured magnetic fields is discussed, with particular reference to sunspots. The modes of oscillation of an isolated flux tube are reviewed.

The problem considered is that of small amplitude vertical oscillations of a viscous isothermal atmosphere. The viscosity coefficient μ is assumed to be constant. (D) An equation for the resonance can be derived when the atmosphere is adiabatic and when it is isothermal. The resonance occurs if the magnetic field strength is.

Eqs. ()–() represent Small oscillations of a viscous isothermal atmosphere book conservation of momentum, the conservation of mass, and the conservation of thermal energy respectively.

From the thermal energy Eq. (), we see that the density and pressure are related, and in general ρ = f (P, T).But in such an atmosphere, acoustic waves will exist as well as gravity waves, and this can lead to complications.

Parcels of air (small volumes of air) in a stable atmosphere (where the temperature increases with height) can oscillate up and down, due to the restoring force provided by the buoyancy of the air parcel. The frequency of the oscillations are a measure of the stability of the atmosphere.

Despite its numerical challenges, finite element method is used to compute viscous fluid flow. A consensus on the cause of numerical problems has been reached; however, general algorithms—allowing Small oscillations of a viscous isothermal atmosphere book robust and accurate simulation for any process—are still missing.

In nonideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section.

It can be successfully applied to air flow in lung alveoli, or the flow. You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them.

The bulk modulus k is defined by dρ/ρ = -dp/k, where k has the dimensions of the pressure p. The fractional change in density must be small for this linear approximation to be valid.

For an isothermal process in an ideal gas, p = ρRT/M, where M is the molecular weight of the gas. In this case, k = p, and holds over a wide range of p. This book has been cited by the following publications.

If the temperature remains constant (isothermal) while you squeeze, Boyle's law would tell you that PV=constant, so if V becomes half as big, the pressure becomes twice as big. But, you have to allow energy to flow out of the bottle in order for the temperature to remain constant; one way to do this is to squeeze very slowly so that the.
