RASCHET KOEFFICIENTOV TEPLO I MASSOOTDACHI V STVOLE NEFTYANOY SKVAZHINY S ISPOL'ZOVANIEM K - E MODELI TURBULENTNOSTI
Abstract and keywords
Abstract (English):
The comparative analysis of calculations of a heatmass exchange is made at the pulsation cleaning of an oil well. Calculations were made within quasistationary and standard model of turbulence. Results on coefficients warm массоотдачи, poluchenenny in calculations for standard of model of turbulence testify that effects the local effects connected with processes of dissipation of kinetic energy in a turbulent stream of liquid and in an interface of dissipation of kinetic energy of a stream play an essential role for organic solvents. For water these effects are insignificant. Here the divergence makes about 20%. Power efficiency of cleaning of an oil well in the pulsation mode for various solvents is defined.
