Viktor Dilman

Viktor Dilman is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Viktor Dilman rather than just read about it. In short: Viktor Vasilyevich Dilman, also spelled Dil'man (Russian: Виктор Васильевич Дильман, born March 11, 1926, in Proskurov (now Khmel’nitskiy), Ukrainian SSR, Soviet Union) is a Russian scientist performing research for USPolyResearch. He is best known for his work in chemical engineering and hydrodynamics including the approximate methods for solving nonlinear differential equations of mass, heat, and momentum transfer…

Key takeaways

Viktor Dilman belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Viktor Dilman to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Viktor Dilman from memory before moving on to harder problems.

Reference excerpt

Viktor Vasilyevich Dilman, also spelled Dil'man (Russian: Виктор Васильевич Дильман, born March 11, 1926, in Proskurov (now Khmel’nitskiy), Ukrainian SSR, Soviet Union) is a Russian scientist performing research for USPolyResearch. He is best known for his work in chemical engineering and hydrodynamics including the approximate methods for solving nonlinear differential equations of mass, heat, and momentum transfer; mathematical modeling of chemical reactor processes and catalytic distillation; heat, mass, and momentum transfer in turbulent flow; fluid dynamics in granular beds; surface convection (Marangoni instability), absorption, and molecular convection.

Biography Dilman received MS in cryogenic engineering from the Moscow Institute of Chemical Engineering (1947), PhD in chemical engineering from the All-Union Research Institute of Oxygen Engineering (Moscow, 1953), and DSc in chemical engineering from the Institute of Nitrogen Industry and Organic Synthesis Products (Moscow, 1968). His major job track record includes head of ammonia synthesis laboratory at the Institute of Nitrogen Industry and Organic Synthesis Products (1965 to 1988); lead researcher at the Kurnakov Institute of General and Inorganic Chemistry, Russian Academy of Sciences (1988 to present); professor at the Moscow Physicotechnical Institute (1981 to present); senior researcher (2005 to present) at USPolyResearch.

Major scientific achievements Dilman developed several approximate methods for solving complicated mass, heat, and momentum transfer problems; proposed a wave model for describing the longitudinal dispersion in turbulent flow; identified the conditions at which the Marangoni effect can occur; showed that the diffusion evaporation mode in unsteady evaporation of liquid into gas may lose its stability if the molecular weight of the evaporating liquid is smaller than that of the gas in contact with this liquid. The total number of published papers and books is more than 300. Currently serves on the Editorial Advisory Board of Theor. Found. Chem. Eng.

Worked examples

Example 1 — a first encounter with Viktor Dilman

Start with the simplest possible case. Write down what Viktor Dilman claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Viktor Dilman before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Viktor Dilman ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Viktor Dilman

In research: Viktor Dilman appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Viktor Dilman in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Viktor Dilman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, Living people, Soviet chemical engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Viktor Dilman outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
