Geothermal Aided Power Generation (GAPG) technology is a geothermal hybrid power system that energy has been integrated into the fossil fired plant to preheat feedwater, and displace extraction steam of plant. In such system, heat exchange process between geo-fluid occurs in between. When exchanger quench lower temperature for transfer purpose, silica scaling would occur system. The performance...

The paper considers the integration and joint operation of a methane steam reforming unit (MSRU) heat pump (HPU) at thermal power plant (TPP) as one possible ways to follow global decarbonization policy. Research methods are simulation modeling in program “United Cycle” analysis thermodynamic cycles pumps. Petrozavodskaya combined (CHPP) was selected object research. During research, technologi...

Conservation of energy usage is essential in chemical process plants due to the expanded users and demands alongside carry-on hike prices. This study analyzed performance savings a heat exchanger network (HEN). It based on decreasing utility while increasing process-to-process exchange HEN using path combination approach at different recovery temperatures (HRATs). The generates combined options...

To investigate the dynamic behavior and flame acceleration of spherically expanding hydrogen flames under low-pressure conditions, deflagration experiments were conducted in a closed combustion chamber. The was observed by high-speed Schlieren imaging, radius propagation velocity measured analyzing photography. When sufficiently small, smooth surface observed, where stretching affected strongly...

In this paper, we critically analyzed possibilities of probability density function (PDF) methods for the closed-form description combustion chemical effects in turbulent premixed flames. We came to conclusion that concept a classical modeling strategy PDF method based on use reaction-independent mixing models is not applicable The reason strong dependence reactions due thin-reaction-zone natur...

Velocity dilatation and total, solenoidal, dilatational dissipation rates of the total flow kinetic energy are extracted from three different direct numerical simulation databases obtained by independent research groups using codes methods (e.g., single-step chemistry complex flames) six premixed turbulent flames associated with flamelet, thin reaction zone, broken zone regimes burning. The res...

This work presents an investigation of fundamental combustion properties, specifically laminar burning velocity and ignition delay time, Alcohol-to-Jet Synthetic Paraffinic Kerosene (AtJ-SPK). Used in blends, this fuel is a sustainable aviation that consists mostly two long-chained, highly branched alkanes. Laminar velocities were measured at preheat temperature 473 K pressures 1 3 bar using th...

This study focuses on the modelling and simulation of an existing active forced circulation solar water heating system in College Science Technology under Royal University Bhutan. The installed prototype consists five flat-panel collectors connected parallel, with a gross surface area 10 m2, 500-litre storage tank built-in heat exchanger to preheat student mess. TRNSYS (Transient System Simulat...
