dc.descriptionThe offset serpentine layout exhibited a larger temperature drop on the floor surface compared to the counterflow layout. A comparison of the two layouts showed that the counterflow layout had lower pressure gradient and turbulent kinetic energy. The temperature near the bend region was influenced on changing the bend radius. Increasing the bend radius from 2mm to 30mm led to an increase in the temperature near the bend, while for bend radii above 40mm, the temperature near the bend region slightly decreased for a constant mass flow rate. Additionally, for the counterflow layout with change in inlet position, with a mass flow rate of 0.23lps, the temperature at the outlet was slightly higher, reaching 320K, and the overall temperature on the floor surface reached 310K.en_US
dc.description.abstractA hydronic radiant underfloor heating system (RFHS) is a type of heating system that utilizes water as the heat transfer medium to provide comfortable and efficient heating in residential and commercial buildings. The rate of energy consumption on the household level for heating and cooling is increasing annually. Meeting future heating and cooling energy demand by alternative technology like floor heating systems (FHS) is a primary concern for engineers and designers. FHS has the advantages of lower investment cost, lower energy consumption, better thermal comfort, and maintaining the desired temperature up to human height. This merit has encouraged many researchers to study FHS in terms of temperature distribution, energy analysis, thermal analysis, and control strategy throughout the world. This study aims to investigate the effect of bend radius and change in the inlet position of pipe on temperature distribution over the floor surface for different mass flow rates. The findings of this analysis will provide valuable insights into the optimal bend radius, and temperature distribution which will provide improved designen_US
