An Elementary Analysis on Ventilated Helmets Using Computational Fluid Dynamics
Abstract: AbstractThis paper focuses on the elementary analysis of a motorcycle helmet using computational fluid dynamics (CFD). The designs of the helmet chosen for the analysis are open face, closed face, and open face with human skull inside. The analysis was done on various speeds of airflow. However, in this paper we will be giving a more generalized idea considering only one velocity of the airflow. We used ANSYS (fluent) for …

A Review on Magnetorheological Fluids and its Stabilization Techniques
Abstract: AbstractMagnetorheological fluids are fluids which can alter its physical and rheological properties in response to an external magnetic field. They find many applications in shock absorbers, semi-active dampers, clutches, brakes, haptic actuators and devices. The rheological properties of these fluids can be altered using additives in the fluid composition and hence, the limitations due to settling tendency can be reduced to an extent. Hence, a detailed study on stabilization of …

A Review on Leak Detection Techniques in Water Distribution Systems
Abstract: AbstractWater is an important resource. Water distribution network (WDN) which includes pipes is used to transport water from water treatment plants to homes. Every water distribution system (WDS) fails partially or completely during its lifetime. This paper gives the in-depth review of leakages caused in WDS. It provides the overview of various techniques implemented towards the occurrence and localization of leaks. This paper organized and classified the techniques into different …

Structural and Thermal Analysis of Ball Control Valve: A Review
Abstract: AbstractA ball valve is a type of flow control device, which is widely used to regulate a fluid flowing through a section of pipe. Currently, analyses and optimization are of special important in the design and usage of ball valves. For the analysis, finite element method (FEM) is often used to predict the safety of valve disc, and computational fluid dynamics (CFD) is commonly used to study the flow characteristics …

Study of Effectiveness of Cone Cruciform Vortex Breaker Device in Reducing the Swirl Angle by Modifying the Number of Vanes Using CFD Technique
Abstract: AbstractMany of the large-scale vertical pumps installed in various pumping stations have experienced some sort of vibration, impeller damage due to local cavitation, excessive bearing wear, or loss of pumping efficiency, combinations of which are considered to be caused primarily by undesirable pump approach flow conditions such as vortices, swirl in intake structure, and inappropriate geometrical layout surrounding the bellmouth. Conventional fixes to resolve these problems include vortex breaker devices …
