Negative skin friction and Neutral plan on the pile in collapsible soil:A Review Study
Abstract: The use of the pile in geotechnical engineering has become interesting due to the many challenges facing the installation process and the problems that may occur suddenly during construction if it is not taken into account. construction of piles in collapsing soil such as soft soil or gypsum soil leads to losses in the bearing capacity of the pile by creating an imaginary additional loading that is above the pile …

A Review on Aerodynamic Improvement of Vehicle
Abstract: The effect of air flow surrounding a vehicle-on-vehicle performance and fuel efficiency is studied. Theproject's major goal is to reduce pollution, global warming causes, and energy consumption bylowering the drag coefficient of road vehicles and thereby improve fuel economy. Aerodynamics is thestudy of the air flow inside and around the body. Because air is a thin fluid, fluid dynamics is also usedto describe it. Speed, mileage, and handling are all …

Hybrid Numerical–Artificial Neural Network Study of Chemically Reactive MHD Nanofluid Flow Incorporating Thompson–Troian Slip and Stefan Blowing
Abstract: Boundary layer behaviour in chemically reactive nanoliquid is significantly affected by surface conditions, magnetic fields, heat and mas transfer mechanisms. However, the combined impact of Stefan blowing and nonlinear Thompson–Troian slip under inclined magnetic fields remains mostly unexplored, particularly in mixed convection flows. In this research work, the flow of a chemically reactive nanoliquid over a permeable surface is investigated by considering the Troian slip, inclined magnetic fields, Stefan blowing, …

Coupled Magneto–Thermal–Diffusion Transport in an Unsteady Maxwell Polymer Fluid with Activation Energy over a Porous Stretching Surface
Abstract: The present study investigates the combined effects of activation energy and diffusion-thermo (Dufour) processes on unsteady magnetohydrodynamic (MHD) flow, heat, and mass transfer of a Maxwell viscoelastic fluid past a porous exponentially stretching vertical sheet. The electrically conducting and incompressible polymeric fluid flows through a saturated porous medium under a transverse magnetic field. The governing momentum, energy, and concentration equations are transformed into nonlinear ordinary differential equations using similarity transformations …

MHD-Assisted Flow Regulation of Viscoelastic Polymer Fluids for Industrial Cooling and Composite Fabrication with Isotherml Plates
Abstract: This study investigates the magnetohydrodynamic (MHD) regulation of viscoelastic polymer fluid flow over a permeable plate, emphasizing its relevance to industrial cooling and composite fabrication. An incompressible, electrically conducting viscoelastic fluid is analyzed under a transverse magnetic field with Hall and ion-slip effects to capture electromagnetic alterations in polymer transport. The governing non-dimensional equations for momentum, temperature, and concentration are solved analytically using the perturbation method. The results show that …

Polymer Chemistry in Shoulder Orthotics
Abstract: The design of effective shoulder orthotic devices has increasingly made use of polymeric materials because of their versatility, durability, and biocompatibility. This review illustrates polymer chemistry role in constructing an orthotic device for shoulder subluxation, which is a commonly occurring post stroke or injury condition. Proprietary design elements such as polypropylene are rigid yet moldable which help in anatomical formulating for joint stabilization. On the other hand, rubber elastomers, medicinal …

Development and Optimization of Cold Rolled Slitting Machine Process
Abstract: Slitting machine is now widely used for dividing a wide strip into a plurality of narrow strips or for trimming the unnecessary or unacceptable edge portion of relatively wide sheet metal stock. In some cold rolling slitting machine a problem has been found that the camber is formed at the time of cutting. When the strip passes through skin pass operation, burr is formed due to friction which will result …
