Droplet Drag Modeling on Spray Conditions
… the effect of droplet deformation and internal circulation on droplet dynamics. Although droplet drag is a classical area of study, there are still theoretical gaps in understanding the motion of large droplets. In applications such as spray combustion, droplets of various sizes are …

A droplet evaporation model for high temperature and pressure spray applications
… effective conductivity model which accounts for internal circulation. The single droplet evaporation model has been implemented and tested into the KIVA multidimensional simulation which models gas flows, sprays, and chemical reactions in internal combustion engines. The new model has been tested …

Urban Design for a Local Merchant Community: the Case of `Uptown' Bellevue, WA
… with existing pathways to create continuity and internal circulation, providing secondary pedestrian travel ways through the site. Lastly, the development layout provides public spaces adjacent to vibrant private commercial areas.

A Numerical Study of the Multi-Component Effects on the Combustion and Evaporation of Biofuels and Blends
… of the distribution function. Finite diffusion, internal circulation, surface regression and high pressure effects are all accounted for. The model is shown to reproduce in a satisfactorily manner, experimental measurements adopted from the literature. The model is applied to predict the …

Advanced anaerobic treatment for energy recovery and improved process economics in the management of biorefinery wastewaters
… the chosen anaerobic treatment technology. The internal circulation (IC) reactor, a high-rate anaerobic treatment system, was selected because of its unique ability to handle high-strength wastewaters consistent with biorefinery operations, while recovering energy and significantly reducing the …

Adaptation of an architectonic tradition for a sustainable future in the Middle East: a case study of three building typologies in Riyadh City.
… organization in Arab homes to improve the internal circulation of air, which helps to cool the various spaces homogeneously. Saudi Arabian regions can benefit from recognizing the need to have designs that address the effects of both warm temperature and humidity level.

A further study of transportation problems on South African university campuses
… of access to and egress from the campus; internal circulation on the campus (whether of vehicles or pedestrians); and parking on the campus. Universities were asked to rank in priority order a series of problem statements. Using their replies as a base, a questionnaire was drawn up, and …

Tree-limit ecotonal response to Holocene climate change in the Scandes Mountains of west-central Sweden
… perturbations is unclear, but a coupling to internal circulation dynamics of the North Atlantic Ocean is hypothesized. Chronologies of the geological archives studied within the project were based on radiocarbon dating and tephrochronology. At Lake Stentjärn, three Holocene cryptotephra …

Fluid dynamics of single levitated drops by fast NMR techniques
… droplets within the continuous medium induces internal fluid motion driven by momentum transfer at the drop surface. This convective transport greatly enhances mass transfer and increases the efficiency of an extraction column dramatically, compared to fluid motion solely governed by diffusion. …

Stoffaustausch und Stoffanreicherung bei zweiphasigen Gegenstromverfahren
… that the enrichment occurs on grounds of an internal circulation of the tracer. The same effect was predicted by K. H. Schubert and E. Steinmetz on the basis of theoretical considerations for a counterstream channel; it is confirmed, this work for the first time experimentally for a counter …
