Dimensional formula is the expression showing the powers to which the fundamental units are to be raised to obtain one unit of a derived quantity. Understand the dimensional formula with examples, and FAQs.
Active nematics are driven, non-equilibrium systems relevant to biological processes including tissue mechanics and morphogenesis, and to active metamaterials in general. We study the three-dimensional spontaneous flow transition of an active nematic in
1. In the soil layer, 2H, kv, Es, η and q(t) represent the thickness, permeability coefficient, modulus of compressibility, viscosity coefficient and time-dependent loading, respectively. Based on the assumption of Terzaghi’s consolidation theory [1], the 1D consolidation equation under time-...
Once the maximum packing fraction can be practically calculated on the basis of the particle size distribution data, the parameter n is the only parameter unknown for calculation of the viscosity of a suspension system. Since the parameter n scales the particle-interaction, one may need to conside...
2c). The UV–Vis absorption spectra in toluene and dichloromethane (DCM) show a strong absorption peak at 284 nm, which can be attributed to the π–π* transitions of the AMID23, and a broad absorption band at 309~376 nm. The absorption extinction coefficient (Supplementary Fig. 3a...
摘要: In this work, we consider the convergence of the Navier–Stokes flow to the Euler flow at small viscosity in a general 2D domain and derive some explicit asymptotic formulas for the convergence at small viscosity under some smoothness assumptions on the solution of the Euler flow....
where λλ is the space wave number; KjKj is the G–S algorithm coefficient (can be obtained from equation (2) [22]); WW is the half-width and LL is the half length of the rectangular loop in meters; J1J1 is the first-order Bessel function; ¯¯¯z0=iωμ0z0¯=iωμ0 ...
In this chapter, we first discuss the stochastic calculus of multi-dimensional diffusion processes with semi-smooth functions, and we derive the Tanaka formula for multi-dimensional semi-smooth functions with the local time on the semi-smooth curve along its gradient direction. With this formula, ...
A series of numerical experiments have been carried out using linear and quadratic bottom friction formulae. The coefficient of linear bottom friction was given by Hunter's formula (1975. Estarine and Coastal Marine Science 3, 473–475), taking into account that the oceanic flows in shelf seas...
