Development of a two-dimensional mathematical model of flow boiling heat transfer in micro- and minichannels [PDF]
EPJ Web of Conferences, 2022 The paper concerns flow boiling heat transfer in micro- and minichannels. In the mathematical model, the steady state heat transfer process in a single asymmetrically heated minichannel was considered.

Bending Solution for Simply Supported Annular Plates Using the Indirect Trefftz Boundary Method [PDF]
Civil Engineering Infrastructures Journal, 2016 This paper presents the bending analysis of annular plates by the indirect Trefftz boundary approach. The formulation for thin and thick plates is based on the Kirchhoff plate theory and the Reissner plate theory.

Temperature Identification in the Structural Elements of Non-Contacting Face Seals by Using Trefftz Functions [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2014 Phenomena of the heat transfer in non-contacting face seals was described by partial differential equation of the second order and boundary conditions. In this way, the mathematical model was developed for the sealing rings.

Coupling techniques of Trefftz methods
Computer Assisted Methods in Engineering and Science, 2022 The Trefftz method pioneered by Trefftz [71] in 1926 is described as follows: The particular solutions or the fundamental solutions are chosen, a linear combination of those functions is regarded as an approximate solution of partial differential ...

Computer Assisted Methods in Engineering and Science, 2023 The author's algebraic theory of boundary value problems has permitted systematizing Trefftz method and expanding its scope. The concept of TH-completeness has played a key role for such developments. This paper is devoted to revise the present state of

A spacetime collocation Trefftz method for solving the inverse heat conduction problem
Advances in Mechanical Engineering, 2019 In this article, a novel spacetime collocation Trefftz method for solving the inverse heat conduction problem is presented. This pioneering work is based on the spacetime collocation Trefftz method; the method operates by collocating the boundary points ...

A Mixed Stress/Displacement Approach Model of Homogeneous Shells for Elastodynamic Problems
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 This paper presents the development of a model of homogeneous, moderately thick shells for elastodynamic problems. The model is obtained by adapting and modifying SAM‐H model (stress approach model of homogeneous shells) developed by Domínguez Alvarado and Díaz in (2018) for static problems.
