The "two fluid" reactor has a high-neutron-density core that burns uranium-233 from the thorium fuel cycle.

Fluid motion can be said to be a two-dimensional flow when the flow velocity at every point is parallel to a fixed plane.

Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility.

The TVD (true vertical depth) of a well describes the length of a perpendicular line from the surface to the bottom of the well.

Twin-turbo refers to an engine in which two turbochargers compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine).

Projects that companies perform from design to completion when it is ready to hand over to the client.

Turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity.

In fluid dynamics, turbulence kinetic energy is the mean kinetic energy per unit mass associated with eddies in turbulent flow.

A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial-flow turbine, through which a high-pressure gas is expanded to produce work that is often used to drive a compressor or generator.

A turbocharger, colloquially known as a turbo, is a turbine-driven, forced induction device that increases an internal combustion engine's power output by forcing extra compressed air into the combustion chamber.

An electric generator powered by a steam turbine connected to its drive shaft.

Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine.

As of 2020, most end-of-use blades are temporarily stored or sent to landfills rather than recycled.

Tundra climates ordinarily fit the Köppen climate classification ET, signifying a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess of 10 °C (50 °F).

The number of blades is selected for aerodynamic efficiency, component costs, and system reliability.

the troposkein is the curve an idealized rope assumes when anchored at its ends and spun around its long axis at a constant angular velocity. A Darrieus wind turbine has blades that approximate the shape of a troposkein to minimize bending stresses.

A tropical savanna climate tends to either see less rainfall than a tropical monsoon climate or have more pronounced dry season(s). In tropical savanna climates, the dry season can become severe, and often drought conditions prevail during the course of the year.

A tropical rainforest climate or equatorial climate is a tropical climate usually found within 10 to 15 degrees latitude of the equator.

Tropical monsoon climates have monthly mean temperatures above 18 °C (64 °F) in every month of the year and a dry season.

A Trombe wall is a massive Equator-facing wall that is painted a dark color in order to absorb thermal energy from incident sunlight and covered with a glass on the outside with an insulating air-gap between the wall and the glaze.
