This book offers an in-depth, up-to-date exploration of flame retardant materials from technical, health, safety, and environmental perspectives. It traces the evolution from traditional halogenated retardants to modern, sustainable alternatives, detailing mechanisms (thermal absorption, barrier formation, gas-phase inhibition, char creation), material classes, and regulatory trends. The volume examines both global and Indian innovations, including bio-based, nanomaterial-enhanced, and phosphorus-nitrogen systems, highlighting risks, benefits, testing standards, and market dynamics. Balancing fire safety with environmental responsibility, it presents vital guidance for researchers, engineers, and policymakers advancing safer, sustainable fire protection technologies.

This book is an expanded and refined version of a master's research project, now presented as a comprehensive study integrating both experimental and numerical methods. The book explores how swirl influences flow behavior, pressure recovery, and efficiency in conical diffusers-key components in aerospace and fluid machinery. The authors designed a transparent Perspex diffuser and introduced swirl using a custom vane-type swirler. Using hot-wire anemometry and Pitot probes, they measured velocity profiles, pressure distribution, and turbulence characteristics. To validate and extend the findings, simulations were performed using ANSYS Fluent with Reynolds Stress Modeling (RSM), ideal for capturing the complex dynamics of swirling flows. The study revealed that swirl at the inlet significantly reduces boundary layer separation and improves diffuser performance, especially when combined with a properly sized tailpipe. Detailed results include CAD models, flow visualizations, and performance plots. This book is a valuable reference for graduate students, researchers, and professionals working in fluid mechanics, turbomachinery, and industrial flow applications.

The work proposed is a stoichiometric equilibrium model to predict the yield of syngas and its composition in the gasification of Prosopis Juliflora in a downdraft gasifier. The deep taproots of this plant cause depletion of the water table, and hence, their removal became a necessity. It is used as firewood for household applications and therefore has great potential to be used as biomass. This work aimed to fill the gap in the literature that does not have experimental or modeled values of syngas yield and composition produced by the gasification of this biomass.
