Comparison of convective heat transfer of turbulent nanofluid flow through helical and conical coiled tubes
Application of nanofluid and coiled tubes are two passive methods for increasing the heat transfer. In the present study, the turbulent flows of water and nanofluid in coiled tubes heat exchanger were numerically studied. CuO-water nanofluid containing 1 vol% copper oxide nanoparticles was used and single-phase approach was considered for nanofluid flow. The effect of different geometrical para...
متن کاملVolumetric and viscometric studies of -alanine in water and ammonia solution at 293- 313K: structure making and breaking effect
The physicochemical properties of solute in solutions provide valuable information on solute –solvent, solute – solute and solvent – solvent interactions. The intermolecular forces between theliquids molecules and solvent molecules affect the viscosity of the solution. Information regardinginter and intra molecular interactions can be obtained from volumetric, and viscometric data in asolute so...
متن کاملNatural Convection from a Helical Heating Coil to the Surrounding Fluid.
An experimental study is reported on natural convection heat transfer from a helical heating coil to the surrounding fluid. The coil is heated electrically and the surrounding fluid is selected to be water. The range of parameters are: Rayleigh number, 879 ?£ Ra ?£ 780168, Prandtl number, 4.22 ?£ Pr ?£ 10.02, dimensionless coil diameter,7.69 ?£ Dave /d ?£ 10.77, number of coil rings, 2 ?£ N ?£ ...
متن کاملWave Motion and Stop-Bands in Pipes with Helical Characteristics Using Wave Finite Element Analysis
Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is f...
متن کاملImproving seismic performance of elevated cylindrical water storage tanks using nonlinear isolators incorporating liquid–structure interaction
Pervasive construction of elevated liquid tanks as the most important sources for urban hygienic water, and their failure under earthquake, highlighs the necessity for research toward new passive control devices. Design and use of base-isolation systems for elevated liquid tanks is propounded as a novel seismic engineering technology. To date, no special examination has been discussed in relati...
