[1] was the first suggest the use of dimple surface for heat transfer Enhancement. Surface dimples are expected to promote turbulent mixing in the flow and Enhance the heat transfer, as they behave as a vortex generator. M. A. Dafedaret. al. [2] studied experimentally the heat transfer augmentation through various geometries of dimpled surfaces in longitudinal and lateral directions. In his paper horizontal

The lockdown has been implemented since last year in most parts of the world to avoid the threat of infection. The entire global economy had somewhat halted for nearly one year. The business sectors including manufacturing, service, education, tourism, agriculture, art, and entertainment have been facing difficulties due to the lockdown [1]. Recently the second wave of COVID 19 has affected India in a brutal way, hence the restrictions are tightened. However, restrictions on the businesses have been imposed to avoid public gatherings and ensure safety measures. The Indian economy is affecting due to these lockdown cycles. Although efforts are being made to adopt alternative working methods, we cannot go ahead with lockdown for a long time. All the activities can be restarted by taking safety measures for the masses. For businesses like grocery shops, hotels, malls; a data analysis tool can be developed which keeps the records of all the visitors along with their health conditions [2]. It can also facilitate the customer to book the time slot in advance for visiting purposes. It can alert the shop owners, customers, and authorities in case of danger as well. The tool will be helpful for small and medium businesses to drive their activities without affecting the safety of customers and other stakeholders. Furthermore, it will help prevents the mob gathering, which is a significant source of community spread of COVID-19.

Research paper thumbnail of Experimental Comparison of Natural Convection and Conduction Heat Transfer

Magnitude of fluid motion is significant in convective heat transfer (the faster the fluid motion... more Magnitude of fluid motion is significant in convective heat transfer (the faster the fluid motion, the greater the heat transfer), while in conductive heat transfer, there is no physical movement of objects undergoing heat transfer. Due to this statement, it is a real fact that convection can be many times faster than conduction. The objective of this research was to compare natural convection and conduction by creating both heat transfer mechanisms in the same product. For this purpose, canned water and 1% agar-gelled water were used in the experimental and further computational fluid dynamics studies. Experiments were conducted at 70C and in boiling water, and ANSYS V.10 (Ansys Inc., Canonsburg, PA) was used in the numerical simulations. The results showed that addition of agar prevented the natural convection phenomena in the gels resulting in pure conduction while the effect of natural convection, which occurred due to thermal buoyancy effects in the given gravitational force fi...
