Working fluids for heat transformers
Heat Recovery Systems and CHP, 1989Abstract A large amount of thermal energy, in the temperature range of 50–90°C, released to the atmosphere by many commercial installations such as agrofeed, paper mills, dairies and process industries, can be upgraded making possible its use in various forms.

How working memory enables fluid reasoning
Applied Neuropsychology: Child, 2017The strong relation between fluid reasoning (Gf) and working memory (WM) is well established. Gf depends on WM to hold necessary information in a span of awareness until the reasoning task is completed. The influence of time constraints on the Gf-WM relation indicates that the abilities to control attention and inhibit interference may be the ...

How Aphron Drilling Fluids Work
Proceedings of SPE Annual Technical Conference and Exhibition, 2005Abstract Aphron drilling fluids, which are highly shear-thinning water-based fluids containing stabilized air-filled bubbles (aphrons), have been applied successfully worldwide to drill depleted reservoirs and other high-permeability formations.

Fluid biaxial banana phases: Symmetry at work
Ferroelectrics, 2000Abstract Fluid biaxial smectics made from compounds without asymmetric carbons but nevertheless with a spontaneous polarization are now known as banana smectics because of their molecular shape. Here we show that symmetry changes under parity (r ← - r) are an efficient way to summarize and differentiate their electro-optic properties.

Haptic Device Working with an Electrorheological Fluid
Journal of Intelligent Material Systems and Structures, 1999A haptic device based on an electrorheological fluid has been designed and tested. The device is similar to ajoystick which controls the motion of a cursor on a computer screen. In electric fields of different strength the shear stress of the electrorheological fluid is increased accordingly, which is perceived by the user by different resistance ...

Leon Lichtenstein’s Work on Rotating Fluids
1999Leon Lichtenstein was professor of mathematics in Leipzig from 1922 until he died in 1933. J. Schauder and E. Kahler were among his students [1]. In 1933, he published a monograph [2] with the title “Gleichgewichtsfiguren rotierender Flussigkeiten” — “Equilibrium figures of rotating fluids” — in which were collected all the work he had done on this ...

Organic Working Fluid Optimization for Space Power Cycles
1991The merits of organic fluid space power cycles are surveyed and compared with those of alternate options. Selection of an optimum working fluid is recognized as an important tool to improve system performance. The main characteristics of organic power cycles are shown to be predictable with a good level of accuracy through a general method, which ...
