Numerical Computation for Modified Cross Model Fluid Flow Around the Circular Cylinder with Symmetric Trapezoidal Cavities

Autor: Rashid Mahmood, Imran Siddique, Ilyas Khan, Mohamed Badran, Sadok Mehrez, Afraz Hussain Majeed, Sehrish Naaz

Publikováno v: Frontiers in Physics, Vol 10 (2022)

This manuscript explores the flow features of the Modified Cross Model in a channel with symmetric trapezoidal cavities in the presence of a circular obstacle. The non-dimensional governing equations and model for different parameters are evaluated v

Mathematical study on two-fluid model for flow of K–L fluid in a stenosed artery with porous wall

Autor: R. Ponalagusamy, Ramakrishna Manchi

Publikováno v: SN Applied Sciences, Vol 3, Iss 4, Pp 1-21 (2021)

Abstract The present communication presents a theoretical study of blood flow through a stenotic artery with a porous wall comprising Brinkman and Darcy layers. The governing equations describing the flow subjected to the boundary conditions have bee

Evolution and Possible Forms of Primordial Antimatter and Dark Matter celestial objects

Autor: Khlopov, M. Yu., Lecian, O. M.

Publikováno v: 25th Workshop on What Comes Beyond the Standard Models?
25th Workshop on What Comes Beyond the Standard Models?, Jul 2022, Bled, Slovenia

The structure and evolution of Primordial Antimatter domains and Dark matter objects are analysed. Relativistic low-density antimatter domains are described. The Relativistic FRW perfect-fluid solution is found for the characterization of i) ultra-hi

Simulation of concrete ageing on dams as illustrated by numerical analysis of Jablanica HPP

Autor: Goran Šunjić, Zoran Milašinović, Alen Harapin, Maja Prskalo

Publikováno v: Građevinar, Vol 71, Iss 09., Pp 749-767 (2019)

The paper presents a model for numerical simulation of interaction between the fluid and the reinforced-concrete structure under seismic load for spatial 3D problems, with an emphasis of concrete dams. The model is based on the so called partition sc

Early dark energy in the pre- and postrecombination epochs

Autor: Adrià Gómez-Valent, Valeria Pettorino, Ziyang Zheng, Christof Wetterich, Luca Amendola

Publikováno v: Phys.Rev.D
Phys.Rev.D, 2021, 104 (8), pp.083536. ⟨10.1103/PhysRevD.104.083536⟩

Many quintessence models possess scaling or attractor solutions where the fraction of dark energy follows the dominant component in previous epochs of the expansion, or phase transitions may happen close to matter-radiation equality time. A non-negli

Opening the reheating box in multifield inflation

Autor: Jérôme Martin, Lucas Pinol

Publikováno v: JCAP
JCAP, 2021, 12 (12), pp.022. ⟨10.1088/1475-7516/2021/12/022⟩

The robustness of multi-field inflation to the physics of reheating is investigated. In order to carry out this study, reheating is described in detail by means of a formalism which tracks the evolution of scalar fields and perfect fluids in interact
