In a groundbreaking study published in ‘Engineering Reports’, Raviteja Surakasi from the Department of Mechanical Engineering at the Lendi Institute of Engineering and Technology in Vizianagaram, Andhra Pradesh, has unveiled significant advancements in the understanding of nanofluids, specifically a propylene glycol and graphene blend. This research employs response surface methodology (RSM) to dissect the viscosity characteristics of this innovative nanofluid, which could have far-reaching implications for the construction sector.
Nanofluids, which are engineered fluids containing nanoparticles, have garnered attention for their potential to enhance thermal conductivity and reduce energy consumption in various applications. Surakasi’s investigation explores the viscosity of the propylene glycol/graphene nanofluid across a temperature spectrum of 40°C to 120°C and weight percentages from 0% to 0.5%. This meticulous analysis aims to bridge the gap between laboratory findings and real-world applications, a challenge that has long plagued researchers in the field.
“The quartic model we developed not only offers double the accuracy of other models, but it also sets a new benchmark for how we understand the behavior of nanofluids under varying conditions,” Surakasi stated. The data revealed that at 120°C, the optimal viscosity of the nanofluid is 0.335 m²/s with a weight percentage of 0.5%. This precise modeling can significantly enhance the efficiency of thermal systems in construction, where temperature management is critical.
The implications of this research extend beyond theoretical advancements. As the construction industry increasingly seeks sustainable solutions, the ability to manipulate the viscosity of nanofluids can lead to improved energy efficiency in heating and cooling systems. This could translate into substantial cost savings and reduced environmental impact, aligning with global trends towards greener building practices.
Surakasi’s work also emphasizes the importance of statistical analysis in modeling, showcasing metrics such as the R² coefficient, coefficient of variation (CV%), and p-values to evaluate model performance. The quartic model’s impressive R² value of 0.9940 indicates a strong correlation between the model predictions and actual viscosity measurements, which is crucial for engineers and developers looking to implement these findings in practical applications.
With the construction sector continually evolving, the integration of advanced materials like graphene in nanofluids could pave the way for innovative solutions in energy efficiency and thermal regulation. As Surakasi noted, “Understanding the detailed behavior of these nanofluids allows us to tailor them for specific applications, potentially revolutionizing how we approach thermal management in construction.”
This research not only contributes to the academic dialogue surrounding nanofluids but also serves as a catalyst for future developments in construction technology. As the industry moves towards more sustainable practices, studies like this one will play a pivotal role in shaping the materials and methodologies of tomorrow.
