Discrete Model Of Heat Exchange Between The Tube And The Heat Carrier Passing Through It, Jurabek Saydullaevich Mamatov, Sardorbek Baxtiyor Ugli Dustnazarov Sep 2020

Discrete Model Of Heat Exchange Between The Tube And The Heat Carrier Passing Through It, Jurabek Saydullaevich Mamatov, Sardorbek Baxtiyor Ugli Dustnazarov

Bulletin of Gulistan State University

Convective heat transfer processes in heat exchangers, which are widely used in industry, are characterized by partial differential equations. Ensuring the adequacy of mathematical models leads to the complication of particular differential equations for products and boundary value problems for them. Acad. A. Azamov and candidate of mathematical sciences M.A. Bekimov proposed a perfect mathematical model of the heat transfer process in rotary regenerative air heaters (RRAH) at thermal power plants in the form of discrete dynamic systems, which made it possible to control the operation mode of RRAH, calculate smoke and air temperature. A mathematical model of the heat …

Change Of Energy At The Movement Of A Fluid Stream, F.A Gapparov, A Kalandarov, S.I Xudaykulov Mar 2018

Change Of Energy At The Movement Of A Fluid Stream, F.A Gapparov, A Kalandarov, S.I Xudaykulov

Bulletin of Gulistan State University

The following article discusses the relationship between the energy of a flow and a change in the free surface, the appearance of the oscillatory process of a turbulent flow. The axial, radial and tangential components of the flow velocity are found, through which the vibrational process of the free flow surface is determined.
