Special Issue Information

Dear Colleagues,

Turbulent flows and heat transfer are intricate phenomena that play a pivotal role in various industrial applications, ranging from aerospace and automotive engineering to energy production and environmental engineering. Accurately modeling and simulating these processes is crucial for ensuring system efficiency, safety, and sustainability. This Special Issue, ‘Advanced Simulation of Turbulent Flows and Heat Transfer’ aims to present and disseminate the latest advancements in this crucial field by inviting researchers and engineers from across the globe to showcase their cutting-edge research, innovative methodologies, and groundbreaking discoveries.

We particularly encourage submissions that utilize artificial intelligence and machine learning in turbulent heat transfer and advanced computational methods, including large eddy simulation (LES), direct numerical simulation (DNS), Reynolds-averaged Navier–Stokes (RANS) models, and hybrid approaches. Topics of interest include, but are not limited to, the following:

  • Numerical modeling, with an emphasis on contributions that enhance the fundamental understanding of turbulent heat transfer processes and their application to engineering problems;
  • Application of artificial intelligence and machine learning in turbulent heat transfer;
  • Turbulent heat transfer in multiphase and porous flows;
  • Flow and heat transfer in biological systems;
  • Instrumentation and novel fluid measurement techniques;
  • Renewable energy;
  • Energy storage systems;
  • Cooling techniques;
  • Combustion, fire, and fuels;
  • Heat pipes and heat pumps;
  • Modeling of environmental flows in natural and built environments;
  • Applications of nano and micro fluids;
  • High-fidelity simulation.

We look forward to receiving your original research papers, empirical studies, or theoretical analyses.

The article presents the results of numerical studies of heat transfer and pressure drops in a channel with transverse micro-fins. The main aim of the study was to prepare the thermal and flow characteristics of such a channel for a variable longitudinal spacing of micro-fins. For the tested pipe with an internal diameter of D = 12 mm, the absolute height of the micro-fins was e = 0.243 mm, which is 2% of its diameter. The tests were carried out for turbulent flow in the range of Reynolds numbers of 5000–250,000 with the variable spacing of micro-ribs in the range of L = 0.28–13.52 mm, which corresponds to their dimensionless longitudinal distance, L/D = 0.023–1.126. For the studied geometries, the characteristics of the friction factor, ft(Re), and the Nusselt number, Nu(Re), are shown in the graphs. The highest values of Nu were observed for a spacing of L/D = 0.092 in the range of Re = 5000–60,000, while the lowest were observed for a geometry of L/D = 0.035 for Re = 60,000–250,000. The friction factors, however, were the highest for the two geometries L/D = 0.161 and L/D = 0.229 over the entire range of the tested Re numbers. A large discrepancy was observed between the friction factors calculated from the Colebrook–White equation (for irregular relative roughness depicted in the Moody diagram) and those obtained from simulations (for pipes with the same roughness height but regular geometry created by micro-fins). An analysis of the heat transfer efficiency of the tested geometries was also presented, taking into account the criterion of equal pumping power, i.e., the PEC (performance evaluation criteria) coefficient. The highest values of the PEC coefficient, up to 1.25–1.28, were obtained for micro-fin spacings of L/D = 0.069 and L/D = 0.092 in the Re number range of 20.000–30.000. Full article
