DNS of momentum and heat transfer inside rough pipes
نویسندگان
چکیده
Abstract. We carry out direct numerical simulation (DNS) of turbulent flow in pipes with a grit-blasted surface, to investigate both on momentum and heat transfer. A wide range Reynolds numbers are considered, while maintaining constant molecular Prandtl number 0.7. The large relative roughness influences the velocity temperature fields, indicating that analogy does not hold at high bulk number.

متن کاملStudy about heat transfer coefficient of water-nanofluid in pulsating heat pipes
Pulsating heat pipe is an efficient heat exchange device which is being used for cooling and heating recovery. In the present work, we made a closed-loop pulsating heat pipe with six U-turns and we used water in our system. Moreover the use of water-Fe3O4 nanofluid was studied with two different filling ratios 40% and 50% and 1% mass concentration. At the end we calculated heat resistance and h...

متن کاملOptimization of Radiative Heat Transfer inside Greenhouses
This paper presents a multi-objective procedure based on a fully elitist genetic algorithm, GA, able to optimize the radiative heat transfer inside greenhouses used to grow crops. Details of the genetic algorithm used is presented herein but the focus is on the heat transfer. The decision variables are the tube temperature and tube radius, that affects directly the entalphy heating flow, and th...
