Experimental and Analytical Study of the Electric Potential using Lagrange Polynomials

On Mechanical and Chaotic Problem Modeling and Numerical Simulation Using Electric Networks

“…Thus, and sticking to the subject of electrical analogy, based on the laws of electric circuits, we should mention the first attempts to successfully simulate processes governed by Laplace's equation through the construction of an electrolytic tank [1], or a century later with the use of graphite paper (analog field plotter [2]). More recently, Arvinti et al [3] implemented a laboratory electrical model to solve the Laplace equation in the whole domain, approaching the solutions using Lagrange polynomials. During the decades between 1940 and 1970, large analog equipment consisting of resistors and capacitors were developed that allowed the simulation of heat and mass flow processes both linear, with the 'heat and mass analyzer' of Paschkis and Heisler [4], and nonlinear, by means of the 'differential analyzer' of Karplus and Soroka [5].…”

Temperature Field Calculation and Thermal Circuit Equivalent Analysis of 110 kV Core Cable Joint

“…And the influence of axial heat transfer on the local temperature distribution of the joint was analyzed. Reference [18] takes a T-shaped cable joint as the research object; the influence of material parameter changes in each layer Firstly, temperature field calculation based on the finite element method is carried out for the main body and intermediate joints of 110 kV single-core cables to obtain the core temperature [23,24]. The cable model for the calculation model is YJLW03-Z 64/110 kV 630 mm 2 .…”
