RISA Comparison of Simplified One-Dimensional and Two-Dimensional Analytical Models for Predicting Metallic Recuperator Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance models for high-temperature metallic recuperators considering one and two-dimensional heat transfer are presented. In one-dimensional model, an explicit expression to represent the effect of both the ...
Effect of Rounded Corners on Heat Transfer and Fluid Flow Through Triangular Duct
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbulent flow heat transfer and friction penalty in triangular cross-sectional duct is studied in the present paper. The sharp corners of the duct are modified by converting it into circular shape. Five different models ...
Simulation of Flow and Heat Transfer in Triangular Cross-Sectional Solar-Assisted Air Heater
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ribbed three-dimensional solar air heater (SAH) model is numerically investigated to estimate flow and heat transfer through it. The numerical analysis is based on finite volume approach, and the set of flow governing ...
Innovatively Arranged Curved-Ribbed Solar-Assisted Air Heater: Performance and Correlation Development for Heat and Flow Characteristics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solar radiation is a rich and clean source of energy. It can be collected and converted to thermal energy with the help of flat plate collectors called the solar-assisted air heater. Because of the low coefficient of heat ...
A Note on the Comparative Analysis Between Rectangular and Modified Duct Heat Exchanger
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The plate fin heat exchangers usually have either rectangular or triangular shaped flow passage. In comparison to triangular flow passage, rectangular flow passage gives comparatively higher heat transfer at the cost of ...
Effect of Dimple Intrusions and Curvature Radius of Rounded Corner Triangular Duct on Fluid Flow and Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sharp corner significantly affects the flow through triangular duct. In the corners, flow gets stagnant, which results in poor heat transfer. Therefore, in the present study, one corner of the duct is kept rounded with ...
Impact of Binary Biofuel Blend on Lubricating Oil Degradation in a Compression Ignition Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents lubricating oil performance in a compression ignition (CI) engine fueled with a binary fuel blend of 70% aamla seed oil biodiesel and 30% eucalyptus oil (EU) on volume basis. This blended fuel was stable ...
Binary Biodiesel Blend Endurance Characteristics in a Compression Ignition Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The results obtained on wear assessment from a compression ignition (CI) engine fueled with a blend of 70% amla seed biodiesel (AB) and 30% eucalyptus oil (EU) on volume basis (called AB70EU30). The results showed stable ...
