This paper reports the study of a conceptual gasoline Internal Combustion Engine (ICE) using scroll type rotary device rather than conventional piston as the main engine component.
This paper deals with the comparison between volumetric expanders (screw, scroll and rotary vane) and an Inlet Forward Radial (IFR) micro turbine for the exploitation of an on board Organic Rankine Cycle (ORC) energy recovery system.
In another fun twist they've added robotic actuators to the rotary wheels so the scroll can physically move or spin in place in various scenarios, such as when it receives a notification.
A case study has been conducted to study the performance of small scale scroll-type rotary ICE.
A library of sub models of components with empirical (rotary vane pump and vapor scroll expander), semi-empirical (compact plates condenser) and spatially detailed physical (gas burner and evaporator) models is used to construct a model, using R245fa as thermal fluid.
Jony Ive, Apple's vice-president of design, has overseen a range of watches that boast numerous digital functions including sensory touch, interfacing and "a rotary dial that translate into data" (a scroll button).
Tapping the center of the screen brings up an old rotary phone icon with which you use the scroll-wheel to input numbers.
What bothered us most was the location of the rotary dial, which didn't work for some actions, including scrolling through XM stations.
In this paper, we present results from tests on a small-scale (1 kWel) ORC engine consisting of a rotary-vane pump, a brazed-plate evaporator and a brazed-plate condenser, a scroll expander with a built-in volume ratio of 3.5, and using R245fa as the working fluid.
Whatever material the scroll parts are constructed of, for example, aluminum alloy or titanium alloy, the trend of the compressor delivery with rotary speed is similar.
