Alternative Nanostructures for Thermoacoustic Projectors

Perananthan S., Mayo N.K., Aliev A.E., University of Texas at Dallas, US

Thermophones are highly promising for such applications as high power sonar arrays, flexible loudspeakers, and noise cancellation devices. So far, freestanding carbon nanotube aerogel sheets provide the most attractive performance as a thermoacoustic heat source. [...]

HydroFlame – A Low Carbon Intensity Process for Low-Mobility Oil Recovery

Rao D.N., HydroFlame Technology Resources, INC, US

HydroFlame is a new concept of burning a fuel directly inside a rotating stream of water. Because of the direct contact between the flame and water, very high heat transfer coefficients are achieved which render [...]

Theoretical modelling of nanofluids for heat transfer

Myers T.G., Centre de Recerca, ES

In this talk we will discuss two uses of nanofluids for heat transfer: for cooling purposes and for absorbing solar thermal energy. In the first case we show that a popular theoretical model, which has [...]

Ionic Liquids as Heat Transfer Medium

Schubert T.J.S., Sahin H., Götz M., Bär K., Buchholz D., Stiemke F., IOLITEC Ionic Liquids Technologies Inc., US

Ionic liquids are defined as pure salts with melting points below 100°C. Their high heat capacity, low vapor and incombustibly make them to promising candidates as thermal fluids. A limiting factor thereby is the resistance [...]

Engineered Nanofluids for Heat Transfer and Novel Applications

Timofeeva E.V., Singh D., Yu W., France D., Argonne National Laboratory, US

Nanofluids are the new expanding area in nanotechnology, with applications as wide as biomedical, lubrication, thermal management, energy generation, energy conversion, and energy storage. Variety and unique characteristics of nanomaterials allow for engineering the multifunctional [...]

Nanocarbon Nanofluids: Comparisons Between Morphology and Nanostructure

Vander Wal R.L., The Pennsylvania State University, US

Reported here are experimental results of studies designed to identify the operable mechanisms responsible for the gains in thermal conductivity of nanoﬂuids based on nanocarbons. Comparison of functionalized versus nonfunctionalized nanocarbons addresses the effect of [...]

Heat transfer behaviour of Nanofluids

Nayak A.K., Kulkarni P.P., Singh R.K., Vijayan P.K., Bhabha Atomic Research Centre, IN

Nanofluids are stable colloidal suspensions of nanoparticles, nanofibers, or nanocomposites in common base fluids, These nanofluids can possess properties that are substantially different from their parent materials. Study on nanofluids heat transfer is rather a [...]

Properties of a Newly Developed Carbon-Aluminum Nanocomposite

Yang M., Novak J., Fink R., Brookover J., Jiang N., Applied Nanotech, Inc., US

A unique carbon-based metal nanocomposite comprised of 80% carbonaceous matrix and a dispersed metal component of 20% aluminum material, represents a culmination of efforts in material science and manufacturing processes focused on the advancement of [...]
