The relativistic equation of motion in turbulent jets
نویسنده
چکیده
The theory of turbulent jets emerging from a circular hole can be found in different books which adopt different theories (1; 2; 3; 4) or in specialized articles (5; 6) : in all the models the pressure , p, is equal to zero. The centerline velocity is always taken to be classical. This paper briefly reviews in Section 2 the simplest model of turbulent jets and then investigates in Section 3 the case of relativistic centerline velocity .

Heat Transfer under Double Turbulent Pulsating Jets Impinging on a Flat Surface
In this study, the numerical analysis of turbulent flow and heat transfer of double pulsating impinging jets on a flat surface has been investigated. The unsteady two-dimensional numerical solution for two similar and dissimilar jets was performed using the RNG k-ε model. The results showed that the RNG k-ε model has more satisfactory predictions of the Nusselt number distribution. Comparisons ...

The energy equation for turbulent flow of fiber suspensions was derived in terms of second order correlation tensors. Fiber motion of turbulent energy including the correlation between pressure fluctuations and velocity fluctuations was discussed at two points of flow field, at which the correlation tensors were the functions of space coordinates, distance between two points, and time.
