Abstract: Performance prediction of STPTCS has been studied by enhancement of heat transfer rate using nanofluid, plain twisted tape and nail twisted tape inserts. Nanofluid and twisted tape inserts based STPTCS are commonly used in the area as such as industries, heating and cooling for buildings, thermal power plants, solar cooker, automobiles etc. This paper provides enhancement and performance prediction in heat transfer in absorber tube of concentrator using nanofluid and twisted tape inserts. The results obtained by simulation using C++ program.
