Study of Steam-Induced Convection in a Rotating Vertical Flow Channel

نویسندگان

چکیده

The phenomenon of steam–water direct contact condensation has significance in a wide range industrial applications. Superheated steam was injected upward into cylindrical water vessel. Visual observations were conducted on turbulent jet to determine the dimensionless length compared nozzle exit diameter and maximum swelling ratio as function mass flux at exit, with gas ranging from 295–883 kg/m2s. Reynolds number based jet’s expansion ranged 41,000 93,000. Farther above region, evolved single-phase heated plume, surrounded by ambient water. Mean axial central velocity profiles determined against kg/m2s observe exponential drop mean vertical distance increased. radial distribution within spread be self-similar, profile followed Gaussian function, after proper scaling velocity.

Numerical Solution of Natural Convection in a Vertical Channel.

Natural convection between vertical parallel plates occurs frequently in applications such as solar collectors and cooling of electronic instruments. The problem is a two dimensional developing buoyant flow. In this work, the two dimensional conservation equations are solved numerically for constant wall temperature and constant wall heat flux. The results for the local Nusselt number at the du...

Numerical study of turbulent forced convection jet flow of nanofluid in a converging sinusoidal channel

Research in convective heat transfer using suspensions of nanometer-sized solid particles in base liquids started only over the past decade. Recent investigations on nanofluid, as such suspensions are often called, indicate that the suspended nanoparticles remarkably change the transport properties and heat transfer characteristics of the suspension. Bending walls can also improve heat transfer...

Convection in a vertical channel

The flow generated by heat convection in a long, vertical channel is studied by means of particle imagery velocimetry techniques, with the help of the thermal measurements from a previous paper (Gibert et al 2009 Phys. Fluids 21 035109). We analyse the mean velocity profiles and the Reynolds stresses, and compare the present results with the previous ones obtained in a larger cell and at a larg...
