Momentum transfer in an annular duct with upward gas-Iiquid
flow was studied under the condition that the liquid flowed as a film
only on the inner core of the annulus, the outer wall remaining dry.
Previous workers have studied climbing and falling liquid
films in tubes or on vertical planes....
By various experiments, it has been found that the response
of real materials to external forces is, in general,
nonlinear in character. In classical continuum mechanics,
the use of ordinary measures of strain have forced the
constitutive equations to take complex forms and since the
orders of these measures are...
The flow configurations around and the forces acting on a
circular cylinder with its axis parallel to a nearby plane boundary
and subjected to a uniform flow were investigated. The flow conditions,
which were perpendicular to the cylinder axis and parallel to
the plane boundary were investigated experimentally and theoretically....
The residence time distribution in a tubular flow vessel with
multiple baffles has been investigated. Length of sections between
the baffles, orifice diameter to vessel diameter ratio, and the flow
rates were varied, with the flow always in the laminar regime.
Conductivity measurements, involving tracer impulse response,
were used to...
In this thesis, problems arising in pumping fluids
from the ground are treated. The mathematical theory is
derived for both the time dependent and independent cases.
A numerical method is developed to solve these problems.
Some particular examples are presented and computer plots
are drawn to illustrate the movement of...
The pressure drop for two-phase liquid-liquid flow is theoretically
predicted for each flow regime. Empirical correlations, which
are applicable in all flow regimes, are also presented for holdup as
well as pressure drop.
The experimental study covered bubble and drop flow regimes.
The discontinuous phase was injected by nozzle into...
The subject of fluid-structure interactions (FSI) are a matter concerning the design of any element immersed in a fluid. One of the most critical phenomena embedded within the scope of FSI is the creation of vortex-induced vibrations (VIV). These type of vibrations originate in a given body as a result...
NuScale Power has designed a small modular reactor using natural circulation cooling dependent systems for both steady-state and transient operations. The NuScale Integral Test System (NIST-1) facility was built to supply test data to NuScale Power to verify and validate computer codes for the NuScale Power Mod- ule (NPM) with...
