Impact of non-uniform heat flux conditions on convective heat transfer and energy efficiency in a corrugated tube.

Many contemporary studies often overlook the reality of non-uniform heat generation in various modern heating devices by presuming uniform heat distribution, emphasizing the need for advancements in heat transfer methods. For this purpose, convective heat transfer through a two-dimensional corrugated tube was computationally analyzed for laminar flow region under different heating conditions. Uniform Heat Flux (UHF), Linearly Increasing Heat Flux (LIHF), Linearly Decreasing Heat Flux (LDHF), and Periodic Heat Flux (PHF) were considered on the corrugation wall.

Study of ongoing registered clinical trials on COVID-19: a narrative review.

Background: The dangerous SARS-CoV-2 virus first emerged in China in December 2019 and has rapidly spread worldwide. Currently, it has affected more than 2,850,000 people. No vaccine or drug is available yet, and therefore researchers and scientists are striving to identify potential drugs or vaccines for combating this virus.
