Modeling and Thermodynamic Analysis of Solar Collector Cogeneration for Residential Building Energy Supply

Journal of Engineering, 2022
Concerns about limited energy resources and environmental problems are growing. One of the solutions to increase energy efficiency is to produce it sparsely. In this regard, cogeneration systems are of particular importance. The home sector is one of the

Numerical analysis of flow and heat transfer enhancement in a horizontal pipe with P-TT and V-Cut twisted tape

Case Studies in Thermal Engineering, 2018
In this work, forced convection heat transfer through a horizontal pipe built-in with/without twisted tape-inserts is numerically studied under a uniform heat flux condition. Water is used as a working fluid.

A numerical investigation of the increase in heat transfer in a half-cylindrical container filled with phase change copper rods

Case Studies in Thermal Engineering, 2022
Phase change materials (PCMs) are capable of storing and removing a significant quantity of latent heat from heating storage systems. PCMs such as paraffin wax are used because they store a large amount of energy in a relatively small space while ...

Flow characteristics and velocity fields of a front opening unified pod at open door condition

Case Studies in Thermal Engineering, 2020
Particle contamination decreases product quality in semiconductor industries. Nowadays, the size of the chips and features has significantly reduced; thus increasing the importance of moisture removal from front opening unified pods during manufacturing ...

Effect of glass type variation on overall thermal transfer value (OTTV) and HVAC energy consumption: a case study of the Bank Syariah Indonesia building

Journal of Renewable Energy and Mechanics
The building envelope, particularly the glazing on the façade, is one of the main pathways for solar heat gain into a building, which can increase the Overall Thermal Transfer Value (OTTV), cooling load, and HVAC energy consumption.

The Optimal Design of Heat Sinks: A Review [PDF]

Journal of Applied and Computational Mechanics, 2020
Heat sinks are used in industrial equipment to dissipate the excess heat from their heat-generating parts to the ambient. In the last few years, efforts on manufacturing electronic or mechanical devices with less weight, space, and lower cost were spent.

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses
