Effects of the van der Waals Force on the Dynamics Performance for a Micro Resonant Pressure Sensor
Shock and Vibration, 2016 The micro resonant pressure sensor outputs the frequency signals where the distortion does not take place in a long distance transmission. As the dimensions of the sensor decrease, the effects of the van der Waals forces should be considered.

Generalized van der Waals equation for nonequilibrium fluids [PDF]
Physical Review A, 1983 The inclusion of dissipative fluxes in the set of independent thermodynamic variables leads, among other features, to a modification of the equations of state. Here, we introduce into the van der Waals equation the generalized pressure obtained in extended irreversible thermodynamics and analyze the influence of a shear stress or a heat flux on the ...

On the calculation of phase equilibrium of Thorium using van der Waals model [PDF]
مجله علوم و فنون هستهای, 2020 Thorium is an actinide substance with an atomic number of 90. Natural thorium is radioactive and, although not fissile, it undergoes a nuclear reaction (n, γ) and then beta radiation into a fissile material of the uranium.

Van der Waals-like State Equation for Atmosphere [PDF]
Anuário do Instituto de Geociências - UFRJ, 2020 In this paper, we first analyze the atmosphere as a gas mixture per unit mass, which is governed by Van der Waals equation, considering the main components of the air and their respective critical properties (critical temperature TC and critical pressure pC ).
