A Compendium of Methods for Determining the Exergy Balance Terms Applied to Reciprocating Internal Combustion Engines
TL;DR: In this paper, a compendium of different methods employed in estimating these exergy terms have been reviewed and classified under individual exery terms with necessary descriptions, which will not only provide plenty of information on exergy evaluation methods of IC engines but also allow future researchers to adopt the appropriate one.
Proceedings ArticleDOI
Analysis of Throttle Opening Variation Impact on a Diesel Engine Performance Using Second Law of Thermodynamics
TL;DR: In this article, an analysis of throttle opening variation impact on a multi-cylinder, direct injection diesel engine with the aid of Second Law of thermodynamics is presented, where the engine is run for different throttle openings with several load and speed variations.
Proceedings ArticleDOI
Modeling and optimal design of small HAWT blades for analyzing the starting torque behavior
TL;DR: In this article, a small three-bladed horizontal axis wind turbine (HAWT) is designed to improve its starting torque behavior, the study of the starting torque behaviour, its analysis, and a new approach to smoothen it, is the important part of this work.
Journal ArticleDOI
Experimental Visualization and Analysis of Multiphase Immiscible Flow in Fractured Micromodels Using Micro-Particle Image Velocimetry
TL;DR: In this article, a micro-PIV method is applied to map the flow velocity, both at the throat and near the fracture region of a micromodel, and visualization experiments are performed to study the flow field produced by single-phase and two-phase immiscible flow.
Journal ArticleDOI
