Abstract:

A novel heat exchanger for automotive applications developed by the Heat Transfer and Fluid Flow Laboratory at the Brno University of Technology, Czech Republic, is compared with a conventional commercially available metal radiator. The heat transfer surface of this heat exchanger is composed of polymeric hollow fibers made from polyamide 612 by DuPont (Zytel LC6159). The cross-section of the polymeric radiator is identical to the aluminum radiator (louvered fins on flat tubes) in a Skoda Octavia and measures 720 × 480 mm. The goal of the study is to compare the functionality and performance p

Abstract:

The use of low-temperature solar thermal energy is of vital importance to households both in temperate zones for heating and in Sahelian zones for domestic hot water. This study focuses on the thermal analysis and simulation of an uncovered flat plate collector with parallel tubes using water as the heat transfer fluid. It is based on the analysis of the thermal performance and the careful selection of each component of the system, namely the coating, the absorber, and the insulator, to obtain optimal operation of the solar collector. The equations are presented in such a way that they can be

Abstract:

This paper presents a scratch detection system based on a cubic Bezier curve fitting using a linear scan camera. The objective was to detect the scratch defects of an aluminum flat tube stably in real-time under complex uncertain background noise. To that end, according to the features of the input image of the linear scan camera and the scratch defects, the proposed method first segmented the input image to ten equal sections in a longitudinal direction, and for every section, OTSU thresholding and morphological filtering were used to reduce the background noise. After the image preprocessing

Abstract:

The paper deals with the research on the influence of the shapes of tubes and fins of automobile engine radiators and ethylene glycol coolants of type G12 on the cooling process. This involves cross-flow without mixing of coolant and air. The circular tubes with straight fins are compared with flat tubes with corrugated fins at identical external dimensions of the radiators. The new coolant is compared with the used coolant (10 years of usage) and further with a mixture of the used coolant and the additive (coolant enhancer). The goal is to reduce the heat dissipation time during the cooling p

Abstract:

This study aims to investigate the effect of tube configuration with different bottom fixation components on the energy absorption of a two-segment crash box. The circular tube thickness configuration has two thickness levels, half of the length of the tube has thicker walls (t2), and the other half has thinner walls (t1). The t1 values are 1, 1.5, 2 and 2.5 mm while t2 is constant, 3 mm. Finite element analysis using ANSYS WORKBENCH was performed for the axial load model. The bottom fixation component uses Cutting Die Model (CDM) and Flat Model (FM). Sixteen crash box models were run to pro

Abstract:

Electromagnetic forming (EMF) is a high energy rate forming (HERF) process. It is a high speed forming process using a pulsed magnetic field to form work pieces made of metals such as copper or aluminum alloys with high electrical conductivity. The work piece to be deformed will be located within the effective area of the tool coil so that the resulting type of stress during the forming process is determined by the type of coil used and its arrangement as related to the component. Tubular or structural components can be narrowed by means of compression coils or widened by means of expansion co

These properties were characterized into three regions: the elastic, the uniform plastic, and the ductile damage regions. Standard tensile tests were used to ascertain the elastic and plastic properties up until uniaxial instability. To characterize the ductile damage, a phenomenological model was employed using a decaying exponential f

Abstract:

Photovoltaic-thermal (PV/T) systems integrate photovoltaic and solar thermal technologies into one single system with dual production of electricity and heat energy. A typical arrangement is the direct attachment of PV modules onto a solar thermal collector surface. For a given collector surface area, the overall system energy performance is expected higher than the conventional “side-by-side” PV and solar thermal systems. In the development of PV/T collector technology using water as the coolant, the most common design follows the sheet-and-tube thermal absorber concept. Fin performance of th

Water-energy nexus is a crucial and challenging concern that addressing it is noteworthy for the future of human beings. In addition, freshwater production is a highly energy-intensive procedure. Therefore, developing a suitable solution for this problem is of importance. In the present scenario, solar energy is one of the suitable options for desalination because solar energy is available at a low cost, is clean for the environment, and is widely available. Generally, solar collectors such as flat plate collectors (FPC) and evacuated tube collectors were experimented for desalination applicat
