where γD_ is a dimensionless function, γψ has the unit of a specific capacitance (unit: Fm−2), and Φ has the unit of surface charge density (unit: Cm−2); • Dirichlet boundary conditions for each ion species ni on a subset ∂ΩD,i⊆∂Ω, i=1,…,Mion: (21.23d)...
They include the constant capacitance (CCM), triple-layer (TLM), and modified triple-layer, Stern variable surface charge-variable surface potential (VSC–VSP), generalized two-layer, and the one-pK models. Differences in the surface complexation models lie in the descriptions of the electrical ...
Moreover, for an elemental volume in a transient nonlinear system, capacitance has to be defined in an operational sense, being specifically associated with a chosen location of observation within the elemental volume. Finally, in order to compute fluxes accurately, the time-averaging factor has to...
Cox is the capacitance per unit area. The block uses an explicit approximation to the surface-potential equation, to avoid the need for numerical solution to this implicit equation. Once the surface potential is known, the drain current ID is given by ID=Wμ0LGΔLGmob√1+(θsatΔψ)2[...

Simulating a design instead of auto tuning will only be done if you have no choice because of the difficulties in defining the components mathematically and setting up the model with all the components correctly is far more time consuming. The comment about capacitance in another thread is just ...
Hence the effective capacitance isC = єrє0 4π (R−λ)2 λ (8) Here’s another way to think about this capacitor. Imagine the inner plate is at the mid-mantle point. The effective area is 4π(R −λ)2. There is capacitor gap of λ between mid-mantle and crust. The ...

L and C are the filter inductance and capacitance to filter the PWM (pulse-width modulation) harmonics. It is worth to note that the value of parameters L and C are not precisely known, and they could vary from the nominal amounts in practice. Eq. (5.1) can be converted into standard...
