Impacts of binary chemical reaction with activation energy on MHD thermally radiating blood based hybrid nanofluid flow through shrinking-stenotic artery: Entropy generation and stability analysis

Hybrid Advances
This study investigates numerically the heat and mass transport with entropy generation of MHD human blood as a hybrid nanofluid at the surface of a porous stenotic shrinking artery in the presence of velocity slip and convective boundary conditions ...

A theory of generalised solutions for ideal gas mixtures with Maxwell-Stefan diffusion [PDF]

, 2020
After the pioneering work by Giovangigli on mathematics of multicomponent flows, several attempts were made to introduce global weak solutions for the PDEs describing the dynamics of fluid mixtures. While the incompressible case with constant density was

Spectral properties of solutions for nonlinear PDEs in the turbulent regime [PDF]

, 1999
We consider non-linear Schrödinger equations with small complex coefficient of size 6 in front of the Laplacian. The space-variable belongs to the unit n-cube (n = 3) and Dirichlet boundary conditions are assumed on the cube's boundary. The equations are

Long-Time Behaviour for Solutions of Systems of PDEs Modelling Suspension Bridges [PDF]

We address a damped and forced system of PDEs modelling the dynamics of a degenerate plate with internal piers, where the two unknowns represent the vertical displacement of the central beam and the angular displacement of the cross sections with ...

Estimates and regularity for some fully nonlinear PDEs in conformal geometry [PDF]

, 2021
In this thesis we obtain new estimates and regularity results for some fully nonlinear elliptic equations arising in conformal geometry. Our first set of new results concern local pointwise second derivative estimates for elliptic solutions to the σk ...

On the crest factor for dissipative partial differential equations [PDF]

, 2019
In this work, we have introduced and then computed the so-called crest factor associated with solutions of dissipative partial differential equations (PDEs). By taking two paradigmatic dissipative PDEs, we estimated in an explicit and accurate manner the

Fourier Transform on the Homogeneous Space of 3D Positions and Orientations for Exact Solutions to Linear Parabolic and (Hypo-)Elliptic PDEs

, 2018
Fokker-Planck PDEs (incl. diffusions) for stable Lévy processes (incl. Wiener processes) on the joint space of positions and orientations play a major role in mechanics, robotics, image analysis, directional statistics and probability theory. Exact analytic designs and solutions are known in the 2D case, where they have been obtained using Fourier ...

Positive singular solutions of a certain elliptic PDE

, 2023
In this thesis, we study the existence of positive singular solutions of a system of partial differential equations on a bounded domain. We first consider the solution of the following problem:\begin{equation} \label{base equation} \left\{ \begin{array}{lr} -\Delta w= | \nabla w|^p& \text{in}~~ B_1 \backslash \{0\},\\ w=0 & \text{on}~~ \partial B_1 ...

Positive singular solutions of a certain elliptic PDE

Journal of Mathematical Analysis and Applications
In this paper, we investigate the existence of positive singular solutions for a system of partial differential equations on a bounded domain \begin{equation} \label{main equation of the thesis} \left\{ \begin{array}{lr} -Δu = (1+κ_1(x)) | \nabla v |^p & \text{in}~~ B_1 \backslash \{0\},\\ -Δv = (1+κ_2(x)) | \nabla u |^p & \text{in}~~ B_1 ...
