In consideration of physical and chemical properties of pure substances, speed of sound is one of important quantity which can used to calculate many of other thermo-physical properties such as isothermal compressibility, Joule-Thomson coefficient, isobaric heat capacity and etc. These thermo-physical properties are the main parameters in industrial and chemical processes. Development of accura...

The ability of intermolecular potentials to correctly predict the thermodynamic properties of liquid water at a density of 0.998 g∕cm(3) for a wide range of temperatures (298-650 K) and pressures (0.1-700 MPa) is investigated. Molecular dynamics simulations are reported for the pressure, thermal pressure coefficient, thermal expansion coefficient, isothermal and adiabatic compressibilities, iso...

heat exchangers are the critical components of refrigeration and liquefaction processes. selection of appropriate operational conditions for cryogenic recuperative heat exchanger and expansion valve operating in joule-thomson cooling system results in improving the performance and efficiency. in the current study, a straightforward procedure is introduced to design an efficient joule-thomson co...

Abstract In this paper, the Joule-Thomson expansion of Born-Infeld AdS black holes is studied in extended phase space, where cosmological constant identified with pressure. The coefficient, inversion curves and isenthalpic are discussed detail using a 4-dimensional hole. critical point hole depicted varying parameter charge Q . T-P plane, temperature obtained different We fi...

The genus Echthronomas Forster, 1869 and two species, Echthronomasfacialis (Thomson, 1887) and Echthronomasquadrinotata (Thomson, 1887), are recorded for the fauna of Ukraine for the first time. Descriptions and photographs of species are provided.
