Maximum principles and overdetermined problems for Hessian equations
(ISTE Group, 2021)
In this article we investigate some Hessian type equations. Our main aim is to derive new maximum principles for some suitable P-functions, in the sense of L.E. Payne, that is for some appropriate functional combinations ...
Renormalization functions of the tricritical O(N)-symmetric Φ⁶ model beyond the next-to-leading order in 1/N
(IOP Publishing, 2021)
We investigate higher-order corrections to the effective potential of the tricritical O(N)-symmetric Φ⁶ model in 3-2ε dimensions in its phase exhibiting spontaneous breaking of its scale symmetry. The renormalization group ...
Design and Comparison Analysis of Various Flow Configurations in Bipolar Plates via Numerical Simulation
(Canadian Center of Science and Education, 2021)
Bipolar plates play a major role in the overall performance of fuel cells, hence their proper design and optimization are essential. In this regard, pressure drop across bipolar plates has a major impact on the efficiency. ...
Optimization of a Confined Jet Geometry to Improve Film Cooling Performance Using Response Surface Methodology (RSM)
(MDPI, 2020)
This study investigates the interrelated parameters affecting heat transfer from a hot gas flowing on a flat plate while cool air is injected adjacent to the flat plate. The cool air forms an air blanket that shield the ...
Evaluating velocity and temperature fields for Ranque Hilsch vortex tube using numerical simulation
(Elsevier, 2021)
In this study, a three-dimensional numerical investigation is carried out to study the flow field inside a Ranque-Hilsch vortex tube (RHVT) model. Flow parameters such as velocity, temperature, and pressure are plotted at ...
Forced vibration characteristics of embedded graphene oxide powder reinforced metal foam nanocomposite plate in thermal environment
(Elsevier, 2021)
Dynamic behavior of a new class of nanocomposites consisted of metal foam as matrix and graphene oxide powders as reinforcement is presented in this study in the framework of forced vibration. Graphene oxide powders are ...
Optimal Operation and Planning of Power System Integrated with Reverse Osmosis Water Desalination
(2021-12)
The typical desalination for seawater in the Gulf area relies on thermal desalination, where the water and electricity are co-generated from fossil fuel thermal plants. These thermal plants are well known to increase CO2 ...
Nonlinear Bending and Snapthrough Response of Doubly Curved Laminated Shells
(2021-04)
Shell structures made up of conventional fiber reinforced composite (FRC) laminates find many applications in engineering fields. In contrary to plate structures, shells exhibit two stable equilibrium configurations. Due ...
