Effects of Cap Thickness and Lipid Core Stiffness on Atherosclerotic Plaque Wall Stress
—
by
Rupture of atherosclerotic plaque is related to mechanical stress, plaque geometry and the material properties of plaque tissues. An idea three dimensional coronary artery with eccentric stenosis was modelled, and stress analysis with fluid structure interactions was performed using ADINA in order to investigate the effects of cap thickness and lipid core stiffness on atherosclerotic…

Performance Improvement of Photovoltaic/Thermal (PV/T) Solar Panel by Module Temperature Reduction with Water
—
by
Crystalline is a popular solar panel mainly used in households and public roads. There are two types of crystalline panels: mono-crystalline and poly-crystalline. Mono-crystalline is popular for its higher efficiency compared to poly-crystalline, long-life service, and low investment cost. However, its efficiency drops as the module temperature increases. So, the technique for module temperature reduction…

Observation of Mechanical Behavior of Bolted Joint Using Abaqus Software
—
by
Using Abaqus software offer several advantages, one of which is high tensile strength. of course, tensile strength reflects the maximum amount of stress or tension the bolted joint can sustain at any given time without breaking. Joint member stiffness in a bolted connection directly influences the safety of a design in regard to both static…

Study on Impact of Power Demand and Photovoltaic Power Fluctuation in Standalone Microgrid System
—
by
In the standalone operation mode of the microgrid, the system is significantly weakened due to a lack of inertia support from the conventional synchronous generator. Hence, investigation of the impact of photovoltaic (PV) power variation and load transition on the standalone microgrid system both stability and quality are essential. In this paper, a microgrid system…

Numerical Study of Phase Change Material-Water Storage on Photovoltaic Thermal Module Performance
—
by
Use of phase change material (PCM) in water storage tank to generate tempera-ture stratification that could enhance performance of photovoltaic thermal (PVT) module was investigated by numerical simulation. A commercial PCM, filled in a set of 40 mm diameter spherical capsules contained in a 200-liter water storage tank was used and the storage was integrated…
