Special issue on new trends in heat and fluid flow: applications and recent developments

Heat and fluid flow have an ability to deal with technological-based systems and generally cover a wide variety of fundamental studies, theoretical mathematical modeling and experimental investigations relating to conduction, convection, condensation, boiling and radiation in systems, processes, materials and many other related objects. This issue invited the researchers to present their latest original research findings which are either advances in the state-of-the-art of mathematical methods, theoretical studies or experimental studies that extend the bounds of existing methodologies to new contributions addressing current challenges and engineering problems related to increasing or decreasing the heat transfer distribution. In fact, this issue has served as a platform for innovation and provided up-to-date findings to readers.

In response to the call for papers, round 50 papers were submitted for possible publication. After comprehensive peer review, only one third papers qualified for acceptance for final publication. This special issue comprises the theoretical and experimental research articles that elucidate the research efforts and recent developments on “New Trends in Heat and Fluid Flow: Applications and Recent Developments.” This issue consists of (Agrawal et al., 2021; Akbari et al., 2021; Alanazi et al., 2021; Alkanhal, 2021; Chang et al., 2021; Chen et al., 2021; Dehghan et al., 2021; Hayat et al., 2021; Riaz et al., 2021; Saadun et al., 2021; Safdari Shadloo, 2020; Selimefendigil and Öztop, 2021; Ullah et al., 2021; Xing et al., 2021; Yilmaz, 2021; Youjun et al., 2020; Zaher et al., 2021; Zhang et al., 2020) accepted papers related to fluid dynamics; heat exchangers; heat transfer enhancement; heat and mass transfer in thermal energy; heat and mass transfer in porous media; heat transfer phenomena in biological systems; nanofluids; two-phase/multiphase flows; Newtonian and non-Newtonian fluids; thermodynamics; and numerical simulations and methods. The presented results are discussed with an adequate physical interpretation.

The rest of two third papers could not be accommodated. The submissions may have been technically correct but were not considered appropriate for the scope of this special issue. The authors are from geographically distributed countries such as the USA, Canada, France, China, Romania, Belgium, Turkey, Saudi Arabia, Pakistan, Malaysia, Vietnam, Morocco, Egypt, India, Vietnam and Iran. This reflects the great impact of the proposed topic and the effective organization of the guest editorial team of this special issue. We hope that this issue will not only provide an overall picture and most up-to-date findings to readers from the scientific community working in the field but would also benefit the industrial sectors in specific market niches and end users.

The guest editor would like to thank all authors for contributing their original work to this special issue, no matter what the final decision on their submitted manuscript was. The editorial team would also like to thank all anonymous professional reviewers for their valuable time, comments and suggestions during the review process.
