How does surface roughness affect heat transfer?5 answersSurface roughness has a significant impact on heat transfer. The presence of roughness on a surface affects the flow characteristics and heat transfer coefficients. In the case of a circular cylinder subjected to crossflow, an increase in surface roughness leads to a decrease in the Nusselt number, Strouhal number, lift and drag coefficients. Similarly, in the case of a supercharger with increased channel surface roughness, the heat transfer of the generator gas and nitrogen is affected, resulting in changes in the temperature of the working medium. At the nanoscale level, the roughness of silicon surfaces affects conductive heat transfer across contacts, with a decrease in contact thermal conductance observed for rougher surfaces. Additionally, in the study of single-phase and two-phase cooling performances, an increase in surface roughness leads to improved heat transfer. Overall, surface roughness plays a crucial role in determining heat transfer characteristics in various systems.
What are the Importance of enhancing heat transfer efficiency in double pipe heat exchangers?3 answersEnhancing heat transfer efficiency in double pipe heat exchangers is important for several reasons.

What is the impact of heat on solar panel efficiency?5 answersThe impact of heat on solar panel efficiency is a significant concern. High temperatures can decrease the electrical proficiency of photovoltaic (PV) panels, leading to a decrease in power output. Several studies have explored cooling techniques to mitigate this issue. Heat harvesting devices (HHDs) based on the Peltier effect have been proposed as a cost-effective option to maintain the surface temperature of PV panels within the operating range, thereby enhancing electricity generation and performance efficiency. Active and passive cooling systems utilizing air, water, or phase change materials (PCM) have also been investigated to improve PV system efficiency. Additionally, the use of heat sinks with different geometries, such as rectangular fins, has been shown to increase the efficiency of PV cells by dissipating thermal energy. Another approach involves using forced air draft produced via a fan to mitigate the effects of heat and dust settlement on the panel surface, resulting in increased power output. Furthermore, coating the support frame of a photovoltaic panel with heat-radiating paint has been proposed as a means to rapidly release heat generated in the module, improving power generation efficiency.
