Substrate Integrated Waveguides (SIW) can be used in antenna applications. Leaky waves from a slot array on the top surface of the SIW in this model generate a beam in a certain direction that can be steered by choosing a different operating frequency. Mehr lesen
This model simulates the electrohydrodynamic (EHD) flow of a dielectric liquid around a wire electrode positioned between two parallel flat-plate electrodes. The ion transport is described using the Poisson–Nernst–Planck equations, while fluid motion is governed by the Navier–Stokes ... Mehr lesen
A circular waveguide filter is designed using a 2D axisymmetric model. Six annular rings added to the waveguide form circular cavities connected in series, and each cavity cutoff frequency is close to the center frequency of the filter. The simulated S-parameters show a bandpass ... Mehr lesen
This model calculates the DC breakdown voltage between parallel electrodes in air using a detailed charge transport approach. It is currently one-dimensional for simplicity but can be extended to other gases and dimensions. The results closely match experimental data found in the ... Mehr lesen
This example demonstrates the Lithium-Ion Battery, Single-Ion Conductor interface for studying the discharge of a lithium-ion battery with solid electrolyte. The geometry is in one dimension and the model is isothermal. The behavior at various discharge currents and solid electrolyte ... Mehr lesen
Induction pumps are used in high temperature cooling systems. The principle of operation is equivalent to a linear three phase induction motor. The lack of moving parts and the pumped liquid being kept in a hermetically closed system are clear advantages. This model shows how to simulate ... Mehr lesen
Electrochemical supercapacitors feature relatively higher energy densities than conventional capacitors. With several advantages, such as fast charging, long charge–discharge cycles, and broad operating temperature ranges, electrochemical supercapacitors have found wide applications in ... Mehr lesen
A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... Mehr lesen
Zweck dieser App ist es, die Anwendung der Cyclovoltammetrie zu demonstrieren und zu simulieren. Sie können die Massenkonzentration beider Spezies, die Transporteigenschaften, die kinetischen Parameter sowie das Zyklusspannungsfenster und die Scanrate variieren. Die Cyclovoltammetrie ... Mehr lesen
A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model ... Mehr lesen
