An Elementary Analysis on Ventilated Helmets Using Computational Fluid Dynamics

By Ratnesh Pandey, Ankit Kumar, Surya Avtar Shiva, Mayank Kumar Sherdaya, Anil Melwyn Rego

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

By Binto K Bino, Manish John Monachan

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 …
