We study a nonlinear, moving boundary fluid-structure interaction (FSI) problem between an incompressible, viscous Newtonian fluid, modeled by the 2D Navier-Stokes equations, and an elastic structure modeled by the shell or plate equations. The fluid and structure are coupled via the Navier slip boundary condition and balance of contact forces at the fluid-structure interface. The slip boundary...

An investigation has been made to analyze the effects of viscous dissipation on the heat transfer characteristics for both hydro-dynamically and thermally fully developed, laminar shear driven flow between two infinitely long parallel plates, where the upper plate is moving in an axial direction at a constant speed. On the basis of some routine assumptions made in the literature, a close form a...

The use of energy-saving devices is the most effective method for decreasing CO2 emissions, which an increasingly concerning environmental issue. asymmetric pre-swirl stator has been developed as device and successfully applied to various types vessels. In present study, a flexible material was determine variation in flow around its efficiency. A fluid–structure interaction (FSI) analysis syste...

We consider a viscous incompressible fluid governed by the Navier–Stokes system written in domain where part of boundary can deform. assume that corresponding displacement follows damped beam equation. Our main results are existence and uniqueness strong solutions for fluid-structure interaction an $$L^p$$ - $$L^q$$ setting small times or data. An important ingredient proof consists study linea...

steady hydromagnetic couette flow of class-ii of a viscous, incompressible and electrically conducting fluid through a porous medium in a rotating system taking hall current into account is investigated. heat transfer characteristics of the fluid flow are considered taking viscous and joule dissipations into account. it is noticed that there exists flow separation at the moving plate in the sec...

The article is devoted to the mathematical analysis of a fluid–structure interaction system where fluid compressible and heat conducting structure deformable located on part boundary domain. motion modeled by Navier–Stokes–Fourier displacement described structurally damped plate equation. Our main results are existence strong solutions in an Lp−Lq setting for small time or data. Through change ...

The interaction between a rigid–flexible system and ambient fluid was simulated numerically at Re = 300 by the immersed boundary method. consists of stationary rigid plate upstream closed flexible filament downstream. For different lengths, four typical regimes for motions were observed. As length increases, successively experiences plate-like (P) mode, cylinder-like (C) slender-shape (S) mode ...

Experimental investigations has been done to find out the heat transfer characteristics and friction factor of water based Al2O3 nanofluids as a coolant in  brazed plate heat exchanger. Plate heat exchanger either use horizontally or vertically. The base plate of the plate heat exchanger was kept inclined at (0⁰, 30⁰ ,60⁰, 90⁰). The experimentation have been done on the two different concentrat...
