Béla Karlovitz
Béla Karlovitz (November 9, 1904 – February 29, 2004) was a Hungarian engineer who pioneered research into the generation of electricity directly from a body of hot moving gas without any mechanical moving parts. This process is known as magnetohydrodynamic generation or MHD generation for short. He received his M.E. degree from Technical University, Budapest, Hungary and his E.E. degree from the Federal Institute of Technology, Zurich, Switzerland. Besides his publications in MHD, he is the author of many publications on turbulent flames and combustion instabilities. He was the head of the Flame Research Section, Explosives and Physical Science Division, Bureau of Mines, Pittsburgh, PA. Subsequently, he was with Combustion and Explosive Research, Inc. in Pittsburgh, PA. In combustion, Karlovitz is known as the first to introduce the concept of flame stretch. The Karlovitz number is named after him. It is a non-dimensional quantity defined as: \mathit = k t_c where t_c is the ...

Pápa
Pápa is a historical town in Veszprém county, Hungary, located close to the northern edge of the Bakony Hills, and noted for its baroque architecture. With its 28,549 inhabitants (2024), it is the cultural, economic and tourism centre of the region. Pápa is one of the centres of the Reformed faith in Transdanubia, as the existence of numerous ecclesiastical heritage sites and museums suggest. Due to the multitude of heritage buildings the centre of the town is now protected. Pápa has a large historical centre, with renovated old burgher's houses, cafes, and museums, including the Blue-Dyeing Museum (:hu:Kékfestő Múzeum (Pápa), Kékfestő Múzeum), set up in a former factory which produced clothes and other textiles dyed with indigo blue under a unique method. The town is also noted for its thermal baths, particularly a newly constructed swimming complex, the House of Esterházy, Esterházy family's palace, its grand Roman Catholic church, and Calvinist secondary school; ...

Westinghouse Electric (1886)
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse and headquartered in Pittsburgh, Pennsylvania. It was originally named "Westinghouse Electric & Manufacturing Company" and was renamed "Westinghouse Electric Corporation" in 1945. Through the early and mid-20th century, Westinghouse Electric was a powerhouse in heavy industry, electrical production and distribution, consumer electronics, home appliances and a wide variety of other products. They were a major supplier of generators and steam turbines for most of their history, and was also a major player in the field of nuclear power, starting with the Westinghouse Atom Smasher in 1937. A series of downturns and management missteps in the 1970s and 80s combined with large cash balances led the company to enter the financial services business. Their focus was on mortgages, which suffered significant losses in the late 1980s. In 1992 they announced a major restruct ...

Fluid Dynamicists
In physics, a fluid is a liquid, gas, or other material that may continuously move and deform (''flow'') under an applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them. Although the term ''fluid'' generally includes both the liquid and gas phases, its definition varies among branches of science. Definitions of '' solid'' vary as well, and depending on field, some substances can have both fluid and solid properties. Non-Newtonian fluids like Silly Putty appear to behave similar to a solid when a sudden force is applied. Substances with a very high viscosity such as pitch appear to behave like a solid (see pitch drop experiment) as well. In particle physics, the concept is extended to include fluidic matters other than liquids or gases. A fluid in medicine or biology refers to any liquid constituent of the body ( body fluid), whereas "liquid" is not used in this ...

Magnetic Flow Meter
{{Short description, Device for measuring flow of a fluid A ''magnetic flow meter'' (mag meter, electromagnetic flow meter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. The physical principle at work is electromagnetic induction. The magnetic flow meter requires a conducting fluid, for example, water that contains ions, and an electrical insulating pipe surface, for example, a rubber-lined steel tube. If the magnetic field direction were constant, electrochemistry, electrochemical and other effects at the electrodes would make the potential difference difficult to distinguish from the fluid flow induced potential difference. To show this in modern magnetic flowmeters, the magnetic field is constantly reversed, cancelling out the electrochemical potent ...

Tom Clancy
Thomas Leo Clancy Jr. (April 12, 1947 – October 1, 2013) was an American novelist. He is best known for his technically detailed espionage and military science, military-science storylines set during and after the Cold War. Seventeen of his novels have been bestsellers and more than 100 million copies of his books have been sold. His name was also used on screenplays written by ghostwriters, nonfiction books on military subjects occasionally with co-authors, and video games. He was a part-owner of his hometown Major League Baseball team, the Baltimore Orioles, and vice-chairman of their community activities and public affairs committees. Originally an insurance agent, Clancy launched his literary career in 1984 when he sold his first military thriller novel ''The Hunt for Red October'' for $5,000 published by the small academic Naval Institute Press of Annapolis, Maryland. ''The Hunt for Red October'', ''Patriot Games'' (1987), ''Clear and Present Danger'' (1989), and '' ...

The Hunt For Red October (film)
''The Hunt for Red October'' (alternate on-screen Russian title: ''Красный октябрь'') is a 1990 American submarine spy thriller film directed by John McTiernan, produced by Mace Neufeld, and starring Sean Connery, Alec Baldwin, Scott Glenn, James Earl Jones, and Sam Neill. The film is an adaptation of Tom Clancy's 1984 bestselling novel of the same name. It is the first installment of the film series with the protagonist Jack Ryan. The story is set during the late Cold War era and involves a rogue Soviet naval captain who wishes to defect to the United States with his officers and the Soviet Navy's newest and most advanced ballistic missile submarine, a fictional improvement on the Soviet Typhoon-class submarine. A CIA analyst correctly deduces his motive and must prove his theory before a violent confrontation between the Soviet Red Fleet and the United States Navy spirals out of control. The film was a co-production between the motion picture studios P ...

Yamato 1
''Yamato-1'' is a ship built in the early 1990s by Mitsubishi Heavy Industries, Ltd. at Wadasaki-cho Hyogo-ku, Kobe. It uses magnetohydrodynamic drives (MHDDs) driven by liquid helium-cooled superconductors and can travel at 15 km/h (8 knots). ''Yamato-1'' was the first working prototype of her kind. It was completed in Japan in 1991, by the Ship & Ocean Foundation (later known as the Ocean Policy Research Foundation). The ship, which includes two magnetohydrodynamic (MHD) thrusters, which have no moving parts, was first successfully operated in Kobe harbour in June 1992. An MHDD works by applying a magnetic field to an electrically conducting fluid. The electrically conducting fluid used in the MHD thrusters of ''Yamato-1'' was seawater. In the 1990s, Mitsubishi built several prototypes of ships propelled by MHDD systems. Despite projected higher speeds, these ships were only able to reach speeds of 15 km/h due to constraints imposed by the weight of the supercon ...
