Mixing processes in lakes are key factors controlling light availability for phytoplankton growth, but understanding the contribution of mixing is often confounded by other factors such as nutrient availability and species dynamics. Our study examined this problem in a low pH, geothermally heated lake dominated by one phytoplankton genus and lacking the complexity of nutrient limitation, phytop...

Thermal convection is induced in a rotating differentially heated annulus by using central magnetic force field. The principle of the system used to simulate large scale such as that found planetary interiors or atmospheres but laboratory scaled model investigated geophysical flow fields. Results suggest fluids can be study phenomena microgravity environment. To quantify thermal forcing, rotati...

When hydrogen gas is used or stored within a building, as with a hydrogen-powered vehicle parked in a residential garage, any leakage of unignited H2 will mix with indoor air and may form a flammable mixture. One approach to safety engineering relies on buoyancy-driven, passive ventilation of H2 from the building through vents to the outside. To discover relationships between design variables, ...
