  - INTERNATIONAL JOURNAL OF HEAT AND MASS TRANSFER - Year 2022

  This paper describes a novel numerical reconstruction procedure (NRP) of the velocity field during natural convective heat transfer from a two-sided, isothermal, heated vertical plate based only on the known temperature field obtained, e.g. with a thermal imaging camera. It has been demonstrated that with a knowledge of temperature distributions, the NRP enables the reconstruction of velocity fields by solving the Navier-Stokes...

  - Year 2019

  A new quasi-analytical near-to-far field transformation based on field matching method (field expansion in a base of Hankel functions) is presented. This approach uses finite element method to obtain near field, then the field is expressed in a base of Hankel functions. The evaluated coefficients allow to calculate the field outside the numerical domain, also in a far distance. The main advantage of the proposed technique is avoiding of...

  Dyskutowany jest wpływ domieszkowania MgCNi3 na górne pole krytyczne (H_c2). H_c2 monotonicznie maleje wraz ze wzrostem koncentracji domieszki. Silniejszy wpływ widoczny w przypadku domieszkowania Fe może być tłumaczony poprzez efekt rozrywania nadprzewodzących par Coopera poprzez centra magnetyczne tworzone przez domieszki Fe.

  - MICROWAVE AND OPTICAL TECHNOLOGY LETTERS - Year 2014

  In this article, the discrete Green's function formulation of the finite-difference time-domain (DGF-FDTD) method is proposed for simulation of wire antennas irradiating inhomogeneous dielectric scatterers. Surface equivalence theorem in the discrete domain is used to separate the problem into an inhomogeneous domain and a wire antenna that are simulated with the use of FDTD and DGF-FDTD, respectively. Then, the excitation of the...

  A poorly designed culvert inlet structure causes scouring, which can lead to the collapse of the culvert and significant damage to the neighboring land. A set of laboratory tests was evaluated to examine velocity distribution at the culvert inlet. A three-dimensional acoustic Doppler velocimeterwas used to measure instantaneous flowvelocity upstream of the culvert. The analysis of mean velocities, turbulence strength, and Reynolds...
