Flow Reversal and Pressure pulsation: Innovative technique to enhance flux in Nanofiltration
Abstract: Reduction in Permeate flux with the period of time is the major drawback for the Pressure-driven membrane processes. Concentration polarization and membrane fouling are the two major limitations for the Pressure-driven membrane filtration processes. They lead to the severe flux decline and that need to be controlled for the better process efficiency. The resistance determination provides basis for selection of membrane and appropriate pressure –driven separation process. This paper outlines …

Managing Blow-by in Modern Engines: A Comprehensive Review of Crankcase Ventilation Technologies
Abstract: Blow-by in internal combustion (IC) engines occurs when high-pressure combustion gases escape past the piston rings into the crankcase. These gases typically carry oil aerosols, unburned hydrocarbons, and fine particulate matter, which, if not effectively managed, can disrupt lubrication, accelerate component wear, and contribute to harmful emissions. Effective crankcase ventilation is therefore essential not only for ensuring engine durability but also for meeting increasingly stringent emission regulations. This paper examines …

Optical Fibre Pressure Sensor in Medicine: A Study
Abstract: In the intricate landscape of human health, precise measurement of physiological parameters is paramount for accurate diagnosis, effective treatment, and continuous patient monitoring. Among these vital parameters, pressure plays a critical role – from the subtle pulsatile rhythm of blood flow to the immense force of an intracranial hemorrhage. For decades, traditional electronic pressure sensors have served this purpose, yet they often come with inherent limitations: concerns about electrical interference, …

A Study on Precision Blood Propulsion in Motor-Driven Artificial Hearts
Abstract: The development of biocompatible, energy-efficient pumping mechanisms is pivotal for advancing artificial heart (AH) technology. This study explores a motor-driven centrifugal pump designed to replicate the physiological dynamics of natural ventricles while mitigating complications associated with conventional axial and pulsatile systems. The proposed system employs a brushless DC motor with closed-loop control, integrated with pressure and flow sensors to modulate rotational speed (RPM) and generate biomimetic cardiac output. The suggested …

Revealing the Hemodynamic Orchestra: Contrasting Analysis of Blood Flow Patterns in a Bifurcated Carotid Artery
Abstract: Understanding blood flow patterns in the carotid artery (CA) is crucial for detecting cardiovascular diseases. Computational fluid dynamics simulations compared non-Newtonian (non-Newt) and Newtonian (Newt) models under pulsatile and laminar flow. CA geometry was accurately designed using ANSYS Space Claim & Fusion360, and simulations were run in ANSYS Fluent. Discrepancies between non-Newt and Newt models were found, especially in bifurcation's distal regions prone to plaque. Pressure ranged from 27.870 Pa …

Weldability of Aluminum Alloy Using Pulsed current Tungsten Inert Gas Welding Process forMechanical Properties: A Review
Abstract: In the TIG welding, also known as gas tungsten arc welding, metal components are bonded by applying heat or pressure. Inert gas is used in pulsed current welding to encapsulate the electrodes and weld pools. Tungsten inert gas is used in the complex welding process known as TIG welding. It alternates between amps operating at high and low levels. Here, increasing the current results in improved power production and weld …
