Open Innovation for Circular Business Models: Addressing the Right Challenge at the Right Time
Journal of Product Innovation Management, EarlyView.ABSTRACT Academic Summary In response to escalating societal challenges, such as climate change and resource constraints, this article examines the transition from linear toward circular business models (CBMs). It explores the challenges of CBM transitions and how to tackle them through open innovation.

International Journal of Hydrogen Energy, 1986
Abstract The generation mix of Electricite de France includes a large number of nuclear power plants. This enables E.D.F. to produce cheap off-peak electricity. Therefore electrolytic hydrogen could be produced at low cost. Ammonia manufacturers and other chemical plants are potential consumers.

ON THE COOLING OF GAS TURBINES
Journal of Flow Visualization and Image Processing, 2001This article deals with measurements of convective heat transfer coefficients in three fluid flow patterns that concern both internal and external cooling of gas turbine components; in particular, the flow in a couple of smooth, or ribbed, ducts connected by a 180° sharp turn, a jet in cross-flow, and a jet impinging on a wall for short nozzle-to-wall ...

Industrial gas turbines show performance characteristics that distinctly depend on ambient and operating conditions. They are not only influenced by site elevation, ambient temperature, and relative humidity, but also by the speed of the driven equipment, the fuel, and the load conditions.

Automotive Gas Turbine Regulation
IEEE Transactions on Control Systems Technology, 2004A multivariable model of an automotive gas turbine, obtained from the linearized system equations is investigated. To facilitate vehicle speed changes, whilst protecting the system against thermal damage, control of the power turbine inlet gas temperature and gas generator speed is proposed by feedback regulation. Fuel flow and the power turbine nozzle

Gas turbines and combined cycle gas turbines
2015Gas turbines and gas-steam combined plants are presented in this chapter. Their valuable characteristics in the wide field of thermal power plants are the high power-to-weight ratio, the low emissions (CO2, SOx, NOx and particulate), the not high capital cost, the relatively high load variation rapidity, especially for simple cycle turbine engines, the

Rendiconti del Seminario Matematico e Fisico di Milano, 1948
Sono inizialmente discusse le ipotesi semplificative adottate per i successivi sviluppi termodinamici; e quindi definito il rendimento dell’eventuale scambiatore di calore, insieme a determinati fattori di perdite dello stesso; sono poi caratterizzate le trasformazioni, che si svolgono nel compressore e nella turbina, attraverso le quantita di calore ...
