Technical Risks of Offshore StructuresAround 1902, Sir James Jeans investigated the stability of a self-gravitating fluid. This calculation considers the fate of small-amplitude waves (‘sound waves’) in a fluid which generates its own gravity.

U.S., Canadian, and Mexican Aquaculture,Consider the gas leaving the tailpipe (exhaust) of a jet or rocket. That gas has been heated by chemical combustion, and accelerated to a large velocity in the nozzle of the jet engine.

Nutrient Cycling in Aquaponics SystemsAims of this exercise: learning to work with some of the fundamental equations of fluid mechanics in terms of vector components and exploiting the mathematical properties (“symmetries”) such as incompressibility and the rotation-free property (i.e. no swirls in the fluid).

From Newton to Euler and Navier-Stokes,In ordinary dynamics, as first formulated by Isaac Newton, the motion of a single particle of mass ., following an orbit . under the influence of some force ., is described by two simple equations of motion, the first linking the acceleration . to the force . and the second linking the velocity . to the position change.

Conservative Formulation of the Fluid Equations,There is a formulation of the hydrodynamic equations that is useful for isolating the constants of motion in stationary flows and for the determination of jump conditions at discontinuities in a flow, such as a shock or the interface between two different fluids: a so-called contact discontinuity.

Special Flows,The complexity of the complete set of fluid equations makes finding general solution difficult. This has lead to a number of useful approximations to the equations that apply for flows with special mathematical properties, such as symmetries.
