Heat transfer enhancement through PCM thermal storage by use of copper fins
Enhancement of heat transfer over a cylinder shaped thermal energy storage filled by paraffin E53 by use of radial rectangular copper fins was analyzed. The thermo-physical features of the storage material are determined in separate experiments and implemented to Fluent software over UDF. Advanced t...

| description | Enhancement of heat transfer over a cylinder shaped thermal energy storage
filled by paraffin E53 by use of radial rectangular copper fins was
analyzed. The thermo-physical features of the storage material are
determined in separate experiments and implemented to Fluent software over
UDF. Advanced thermal storage geometry comprehension and optimization
required introduction of a parameter suitable for the analysis of heat
transfer enhancement, so the ratio of heat transfer surfaces as a factor was
proposed and applied. It is revealed that increase of the ratio of heat
transfer surfaces leads to the decrease of melting time and vice versa.
Numerical analysis, employing the 3D model built in Ansys software, observed
storage reservoir geometries with variable number of longitudinal radial
fins. The adjusted set of boundary conditions was carried out and both
written in C language and implemented over UDF in order to define variable
heat flux along the height of the heater. The comparison of acquired
numerical and experimental results showed a strong correlation. Experimental
validation of numerical results was done on the real TES apparatus. |
