Special issue on ME‐NETT 2015

Abstract

Editors Preface

This special issue of ME‐NETT2015 (The 29th Conference of Mechanical Engineering Network of Thailand) contains articles that address challenges in different fields of mechanical engineering. The first paper of this special issue “Flow and mixing in a model swirl combustor equipped with a telescopic end plate porous medium” explores the a non‐reacting turbulent swirl flow in a transparent model swirl combustor equipped with a telescopic end plate porous medium (PM), in an effort to design and developing a future combustion system based on a concept of a PM burner by using PIV technique. The second paper “Performance of highorder schemes on collocated and staggered grids” investigate the decay of homogeneous isotropic turbulence (HIT) using the second‐order to sixth‐order central‐finite‐difference approximations (CDAs) and compare the results with those from the pseudo‐spectral scheme. The third paper “Thermal characteristics in a heat exchanger tube fitted with zigzag‐winglet perforated‐tapes” deals with the enhanced heat transfer and pressure loss characteristics using zigzag‐winglet perforated‐tape inserts (ZW‐PT) in a round tube having a uniform heat‐fluxed wall. The final paper of this special issue “Diversity factor analysis of energy consumption for school building” presents the diversity factor which shows the actual energy consumption and reflects the energy consumption behavior. The editors hope that this special issue will draw reader’s attention to the multi functionalization of mechanical engineering.
