A comment on the theory of turbulence without pressure proposed by Polyakov
نویسنده
چکیده
Owing to its lack of derivability, the dissipative anomaly operator appearing in the theory of turbulence without pressure recently proposed by Polyakov appears to be quite elusive. In particular, we give arguments that seem to lead to the conclusion that an anomaly in the first equation of the sequence of conservation laws cannot be a priori excluded.

June 1995 PUPT-1546 TURBULENCE WITHOUT PRESSURE
We develop exact field theoretic methods to treat turbulence when the effect of pressure is negligible. We find explicit forms of certain probability distributions, demonstrate that the breakdown of Galilean invariance is responsible for intermit-tency and establish the operator product expansion. We also indicate how the effects of pressure can be turned on perturbatively.
متن کاملPriority Setting Meets Multiple Streams: A Match to Be Further Examined?; Comment on “Introducing New Priority Setting and Resource Allocation Processes in a Canadian Healthcare Organization: A Case Study Analysis Informed by Multiple Streams Theory”
With demand for health services continuing to grow as populations age and new technologies emerge to meet health needs, healthcare policy-makers are under constant pressure to set priorities, ie, to make choices about the health services that can and cannot be funded within available resources. In a recent paper, Smith et al apply an influential policy studies framework – Kingdon’s multiple str...
متن کاملTurbulence With Pressure
We investigate the exact results of the Navier-Stokes equations using the methods developed by Polyakov. It is shown that when the velocity field and the density are not independent, the Burgers equation is obtained leading to exact N-point generating functions of velocity field. Our results show that, has to be generelized the operator product expansion, proposed by Polyakov both in the absenc...
متن کاملComparison of different turbulence models in a high pressure fuel jet
In this study, modeling of a fuel jet which has been injected by high pressure into a low-pressure tank are investigated. Due to the initial conditions and the geometry of this case and similar cases (like CNG injectors in internal combustion engines (ICE)), the barrel shocks and Mach disk are observed. Hence a turbulence and transient flow will be expected with lots of shocks and waves. Accord...
متن کاملThe effect of turbulence model on predicting the development and progression of coronary artery atherosclerosis
A severe case of stenosis in coronary arteries results in turbulence in the blood flow which may lead to the formation or progression of atherosclerosis. This study investigated the turbulent blood flow in a coronary artery with rigid walls, as well as 80% single and double stenoses on blood flow. A finite element-based software package, ADINA 8.8, was employed to model the blood flow. The hemo...
