    The analysis of influence of uncertainty factors on mathematical modeling of process of reverse expansion of ammonia in low-speed reciprocating compressor stage. Part 1 by D. Kh. Sadvakasov, G. I. Chernov, V. L. Yusha

    Published 2022-03-01
    “…The mathematical model is based on the equations of the first law of thermodynamics for a body of variable mass, the equation of state of a real gas, the Clausius– Clausius and Newton–Richmann equations. The results of the calculation showed that the instantaneous values of the pressure and temperature of ammonia, as well as its degree of dryness during reverse expansion in the wet steam region, significantly depend on the chosen method for calculating the heat transfer coefficient. …”

    Tensile properties of domestic Al2O3f/Al2O3 composite at room temperature and 1000 ℃ by ZHANG Ke, XU Ping, ZHANG Chao, LI Chenchen, YING Wenqing, XING Ning, LI Mei, ZHANG Chengyu

    Published 2025-01-01
    “…The results show that the room-temperature tensile strength of domestic Al2O3f/Al2O3 is (257±31) MPa while the tensile strength at 1000 ℃ is 78% of room temperature strength, reaching the level of foreign Nextel610/Al2O3. The interfacial bonding is the main factor affecting the tensile strength. …”

    The analysis of uncertainty factors influence on mathematical modeling of ammonia compression in wet vapor area by D. Kh. Sadvakasov, G. I. Chernov, V. L. Yusha

    Published 2021-10-01
    “…The mathematical model is based on the equation of the first law of thermodynamics for bodies with variable mass, the equation of state for real gases, the Clausius–Clapeyron and Newton–Richman equations. When determining the heat transfer coefficient value, several well-known dependencies for calculating these coefficients for dropwise and filmwise condensation have been considered. …”
