A comparison of forced and natural circulation steam generators.
… contained an increasing number of references to forced circulation boilers. Most of these articles extol the virtues of some one kind of boiler or tend to justify the conventional natural circulation principles. The range of boiler types covered by the term "forced circulation" is much broader …

A coupled atmosphere-ocean model of thermohaline circulation, including wind-driven gyre circulation with an analytical solution
A parameter representing circulation due to wind forcing is added to the thermohaline circulation model of Marotzke (1996). The model consists of four boxes and is governed by a system of two differential equations governing the temperature and salinity differences between high latitude ocean and …

Investigation of standard test procedures for integral storage solar domestic hot water systems
… and irradiance levels, both with and without forced circulation and noontime hot water draws. An analytical model was developed to predict the thermal performance of one of the two systems tested and predicted performance was compared with experimental results. Experimental and analytical …

A study of the cleaning and sanitizing of milk pipe lines
… steel, could be satisfactorily cleaned by circulation cleaning procedures as opposed to daily disassembly of the entire pipe line. To facilitate such a determination, two experimental periods of approximately thirty days each in duration were set up. In the first period the experimental …

Tidal velocity asymmetries and bedload transport in shallow embayments
Tidally forced circulation can cause a net near-bed transport of sediment when the tidal velocity is asymmetric about a zero mean (flood or ebb dominant) and the transport rate is nonlinearly related to velocity. The relationship between elevation and velocity is elucidated here to enable one to …

Evaluation of RANS-Based Turbulence Models for the Propagation of Stratified Fronts in Buoyancy-Driven Flow
… natural convection to cool the core in the event forced circulation fails. However, the widely implemented Reynolds-averaged Navier-Stokes (RANS) approach to turbulence modeling has previously shown limitations in its ability to adequately predict buoyancy-driven f lows, including thermally …

Buoyancy-driven circulation in the Red Sea
This thesis explores the buoyancy-driven circulation in the Red Sea, using a combination of observations, as well as numerical modeling and analytical method. The first part of the thesis investigates the formation mechanism and spreading of Red Sea Overflow Water (RSOW) in the Red Sea. The …

LEU+ Fuel Cycle Investigation of the BWRX-300 Design Using Neutronic and Two-Phase Thermal Hydraulic Analyses
… complexity of the BWRX-300 is the use of natural circulation rather than the forced circulation employed by the previous generation of BWRs. This does, however, also remove the ability to extend the cycle by increasing mass flow rate at the end of the cycle, a practice utilized by previous and …

Stability analysis of a natural circulation lead-cooled fast reactor
… hydraulics stability analysis of a natural circulation lead cooled fast reactor design. The stability concerns arise from the fact that natural circulation operation makes the system susceptible to flow instabilities similar to those observed in boiling water reactors. In order to capture …

Subtidal cross-shelf circulation on the Northern California shelf
… (STRESS) study, and Northern California Coastal Circulation Study (NCCCS) are used to study subtidal cross-shelf circulation over the northern California shelf. The northern California shelf, like much of the United States Pacific coast, is subject to strong wind forcing which exhibits …
