Evaporating water drops on a horizontal heated substrate were investigated experimentally. The heater was made of constantan foil with the thickness 25 μ m and size 42 × 35 mm 2 . temperature bottom surface measured by infrared (IR) camera. To determine heat flux density during evaporation liquid near contact line, Cauchy problem for equation solved using data. maximum is obtained in line region exceeds average from entire factor 5–7. wetted drop 3–5. This fact explained influx periphery to...
Abstract The algorithm of reconstruction pressure velocities in a thinly stratified layer and the location gap points medium is suggested. analytic expressions for derivatives residual functional with respect to thin layers by coordinate are obtained. suggested tested numerical examples.
In this paper, the coefficient inverse problem for elasticity system horizontally stratified media is considered. The different numerical experiments solving are presented. with residual functional allow us to formulate minimization strategy in frequency domain. pressure and shear velocities member of thin layers numerically reconstructed by means strategy.
In this paper we introduce the generalization of known technique gradient construction based on conjugate problem for case when unknown function is complex-valued. We notion frequency. The frequency helps to estimate possibility simultaneous determination dielectric permeability and conductivity.
In the paper we numerically solve an inverse problem of determination medium parameters a member thin anisotropic layers for elasticity system. We also investigate case transversely isotropic with symmetry axis lying in plane Oxy. For example, this model can describe vertically fractured medium. present one possible ways numerical solution problem. Examples reconstruction show efficiency algorithm offered.
The paper presents an improvement of the heated thin foil technique, which allows to study nonstationary transport processes. Mathematically, problem is reduced solving heat equation with data on a time-like surface. A new numerical method for its proposed. efficiency proposed calculation scheme demonstrated model example.
