Abstract: Flow characteristics are measured by providing a flow path from a flow supply source through a flow restriction passage. A plurality of movable fins are extendable into the flow restriction passage, resulting in a change in the flow characteristic of the flow restriction passage. The movable fins are controlled and a flow measurement device is used for measuring flow or flow resistance through the flow restriction passage with the movable fins extended and retracted.

Abstract: The system for making suspensions includes a housing, with a platform mounted therein and a translating table slidably mounted on the platform for removably supporting a receptacle. A base fluid tank stores a base fluid, and a solid particle container stores solid particles. A rotating dispenser system is mounted within the housing, above the platform and the receptacle. The rotating dispenser includes a base fluid dispenser for dispensing a controlled mass of the base fluid into the receptacle, and a solid particle dispenser for dispensing a controlled mass of the solid particles into the receptacle. The base fluid dispenser is in communication with the base fluid tank, and the solid particle dispenser is in communication with the solid particle container. A mixer selectively and controllably mixes the controlled mass of the base fluid and the controlled mass of the solid particles in the receptacle to form the suspension.

Abstract: A system and method for producing hydrogen (H2) gas and a magnesium (Mg)-aluminum (Al) based aqueous suspension from pre-prepared effervescent tablets are provided. The produced H2 gas can be stored in a tank or directly utilized in a fuel cell, whereas the produced suspension can be employed as an advanced heat transfer fluid in a variety of thermal applications. Furthermore, the as-prepared tablets are fabricated with a homogeneously mixed and well-compressed mixture of Al particles, Mg particles, and sodium bicarbonate (NaHCO3) powder in a sealed container to prevent air and humidity from reacting with the raw materials. As a result of the chemical reaction between the tablet and water, H2 gas (in the form of bubbles) and the Mg—Al-based suspension are produced simultaneously. This system results in two products (i.e., H2 and suspension) that can be used individually or all at once by integrating the different system components together.

Abstract: A system and method for producing hydrogen (H2) gas and a single or hybrid hydrogen active material based aqueous suspension from pre-prepared effervescent tablets are provided. The produced H2 gas can be stored in a tank or directly utilized in a fuel cell, whereas the produced suspension can be employed as an advanced heat transfer fluid in a variety of thermal applications. The effervescent tablets can be fabricated with a homogeneously mixed and well-compressed mixture of hydrogen active metallic particles and effervescent powder in a sealed container to prevent air and humidity from reacting with the raw materials. As a result of the chemical reaction between the tablet and water, H2 gas (in the form of bubbles) and the hydrogen active material-based suspension are produced simultaneously. This system results in two products that can be used individually or all at once by integrating the different system components together.

Abstract: A water desalination system and process are provided in which a suspension is fed into a water desalination chamber from a source container. At least one effervescent tablet is introduced into a base fluid within the source container to form the suspension. The effervescent tablet serves to increase the heat absorption of the base fluid and enhance the efficiency of the water desalination process. The effervescent tablet used in the process may include multi-walled carbon nanotubes (MWCNT) as well as one or more surfactants and/or effervescent agents such as sodium dodecyl sulfate, monosodium phosphate, and sodium carbonate. Introduction of the effervescent tablet into the base fluid may result in the growth of crystals within the suspension. The presence of crystals in the suspension serving to further enhance the solar radiation and heat absorbance of the base fluid.

Abstract: The fabric with embedded dispensing channels includes a fabric sheet with at least one flexible conduit integrated into the fabric sheet. The at least one flexible conduit has an inlet and a plurality of dispensing holes formed through at least one wall thereof. The at least one flexible conduit is hollow and defines an interior channel. Opposite the inlet, the at least one flexible conduit may have a closed end. A pump, compressor or the like may be fluidly connected to the inlet for transferring a substance into and through the at least one flexible conduit for dispensing through the dispensing holes.

Abstract: An effervescent suspension for metallic quenching and coating purposes, is implemented by providing and an effervescent tablet with mixture comprising a solid alkaline, a solid acid, and noble metal particles. The mixture is added to water to produce a reaction in the water resulting in the release of CO2 gas, which disperses the noble metal particles in the water to provide a suspension. A hot metal material, having a temperature below its melting point, is immersed in the suspension to provide a quenched metal that has a temperature below its melting point in the suspension to provide a quenched metal coated with noble metal particles. The solid alkaline may comprises sodium bicarbonate (NaHCO2) powder and sodium carbonate (Na2CO3) powder. The solid acid may comprise monosodium phosphate (NaH2PO4) powder.

Abstract: The system and method for determining physical stability of dispersed particles in flowing liquid suspensions is performed by passing a fluid with suspended particulates in a column of filter elements having progressively smaller porosities. The fluid is received by a fluid supply receptacle and then passed through the column of filter elements. The filter elements are arranged so that successive filters are downstream of each other, with successive filters having successively smaller porosities. The porosity of an initial filter element has a sufficiently large porosity to filter a largest particle size intended for detection, and a final filter element has at least a sufficiently small porosity to filter a smallest particle size intended for detection. This results in the successive filters separating successively smaller particles from the fluid. Average particle size and particle count are obtained by removing a mesh filter element and performing SEM analysis on the filtered particles.

Abstract: A sample observation container and methods of use thereof are provided. The sample observation container includes a base and one or more sidewalls extending from the base. The one or more sidewalls form a sample enclosure for holding a sample undergoing a sample observation test such as sedimentation photographical capturing and dynamic light scattering, among other tests. The one or more sidewalls form a sample enclosure of adjustable cross-sectional area. The cross-sectional area may be adjusted by feeding or retracting a flexible sheet from a source roll to the sample enclosure. The cross-sectional area may further be adjusted by removing an innermost sidewall from among one or more nested sidewalls. The containers allow for physical adjustment of the cross-sectional area while performing subsequent sample observation tests, thereby allowing assessment of the effects of container size on the results of the sample, such as particles in liquid suspension.
