This is the data of a direct simulation of a hot jet in cold channel crossflow. The adiabatic thermal boundary conditions are applied to the top and bottom wall. Fo details about the computational configurations, methods and results, please refer to "Direct Numerical Simulation of a Low Momentum Round Jet in Channel Crossflow" which has been accepted to Nuclear Engineering and Design, or "DNS of a Jet in Cross Flow with Passive Scalar Mixing" in Turbulence, Heat and Mass Transfert 8, 2015 (see links below) We also have the data of the same configuration but with iso-thermal boundary condition or conjugate heat transfer. A paper discussing the difference of the thermal fields under different thermal b.c. has been submitted to the International Journal of Heat and Mass Transfer. A paper on validating selected RANS models using the current database is under preparation. A paper discussing the coherent structures of current flow using proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD) is under preparation. We have the 3D time-averaged statistics of mean velocity, Reynolds stress, heat fluxes, temperature fluctuations and their budgets. We also have more than 4000 full resolution instantaneous snapshots for each case (only 200 for the adiabatic case). The complete dataset is about 20TB!!! More data will be released in the future. Please feel free to contact me if you need more information or more data.
