Turboprop
A turboprop is a gas turbine engine that drives a propeller, the most fuel-efficient choice for short regional flights at speeds up to about Mach 0.5.
Turbopump
A turbopump is a turbine-driven pump assembly that raises liquid rocket propellants to the high pressure needed for injection into a rocket engine's combustion chamber.
TurboQuant
TurboQuant is a data-oblivious vector quantization algorithm from Google Research, introduced in 2025, that compresses vectors to 3 to 4 bits per coordinate near the theoretical optimum.
Turborepo
Turborepo is an open-source build system for JavaScript and TypeScript monorepos, written in Rust, that caches task outputs so unchanged work is never repeated; Vercel acquired it in 2021.
Turboshaft
A turboshaft engine is a gas-turbine engine that delivers power through a rotating shaft rather than as jet thrust, most commonly to drive a helicopter rotor.
Turbot
Turbot (Scophthalmus maximus, formerly Psetta maxima) is a large left-eyed European flatfish fished from the North Sea to the Black Sea and farmed on shore, with Spain harvesting 10,058 t in 2024 and China the largest farmed producer.
Turbot War
Turbot War: 1995 Canada-Spain/EU dispute over Greenland halibut fishing on the Grand Banks, sparked by Canada's high-seas boarding of the trawler Estai, resolved by an April 1995 quota deal and December 1995 agreement.
TurboTax
TurboTax, originally Macintax, is tax preparation software sold by Intuit that guides users through preparing and e-filing US federal and state income tax returns, online or on desktop.
Turbulence
Turbulence, or turbulent flow, is a state of chaotic fluid motion with swirling eddies, governed by the Navier-Stokes equations and occurring at high Reynolds number.
Turbulence (2025 film)
Turbulence (2025 film), also released as Turbulencia and タービュランス, is a Claudio Fäh survival thriller starring Olga Kurylenko, Jeremy Irvine, Kelsey Grammer, and Hera Hilmar: a couple's Dolomites hot air balloon trip is hijacked by a passenger tied to Zach's past.

Turbulence kinetic energy
Turbulence kinetic energy, usually written k, is the mean kinetic energy per unit mass of velocity fluctuations in turbulence, and the standard measure of turbulence intensity.
Turbulence modeling
Turbulence modeling is the practice of replacing turbulent fluctuations in fluid flow with approximate mathematical models, letting computational fluid dynamics predict drag, heat transfer, and mixing without resolving every eddy.
Turbulent kinetic energy
Turbulent kinetic energy (TKE) is the mean kinetic energy per unit mass of velocity fluctuations in a turbulent flow, central to ocean and atmospheric mixing models.
Turbulent Prandtl number
The turbulent Prandtl number (Pr_t) is a dimensionless ratio of eddy viscosity to eddy thermal diffusivity used in turbulence modeling, a property of the flow, not the fluid.
Turbulent transport
Turbulent transport is the cross-field movement of particles, heat, and momentum in a magnetized plasma driven by microinstabilities rather than collisions, and it dominates energy loss in tokamaks.
Turbulento
Turbulento is a 2006 German children's dexterity and memory board game by Heinz Meister, published by Selecta Spielzeug; 2-4 players age 4+, flipping wooden animal pieces with balls, Kinderspiel des Jahres 2007 recommendation list. Distinct from Sky Team: Turbulence.

Turda
Turda (Potaissa) is a city in Cluj County, Romania, on the Arieș River; Roman seat of Legio V Macedonica, first mentioned as Castrum Turda in 1075, and home of the Salina Turda salt mine, closed in 1932 and reopened in 1992 as a major tourist attraction.
Turdetani
The Turdetani were an Iron Age people of the lower Guadalquivir valley in southern Spain, whom Strabo called the most intelligent Iberians and heirs of the Tartessians.
Turdoides
Turdoides, babblers, a genus of cooperatively breeding Leiothrichidae passerines of Africa and southern Asia; several species moved to Argya; Arabian and pied babblers are key study species.
Turducken
