A numerical model analysis on perforated aerofoil shaped pin fin arrays in heat dissipation enhancement, pressure drop and optimization

Abstract

It is a numerical model analysis on perforated aerofoil shaped pin fin arrays (PASPFAs).The arrays are configured in staggered and inline arrangements. An absolute numerical methodology has been implied. The three dimensional (3-D) numerical investigation has been carried out. A hypothesis set that heat dissipation by the staggered arrangements is high than inline arrangements of perforated aerofoil shaped pin fin arrays (PASPFA). The aerofoil shaped pin fins geometry has been choose to achieve a better streamline pressure drop. A circular geometrical perforation impinged in the aerofoil pin fins. So, one more hypothesis has been set that the heat dissipation rate is high due to perforations in the aerofoil shaped pin fins. Due to perforations in the aerofil pin-fins, there is material savings, optimization, higher heat dissipation rate, improved thermal efficiency (ηAPF), improved overall effectiveness (ε oval. APF) and economical. In the staggered arrangements of aerofoil pin–fin array, there is enough space management from heat dissipation, installation, maintenance and in lesser pressure drop point of view. The perforated aerofoil pin–fin array in staggered arrangement than no perforation and inline arrangement has been verified and satisfied the set hypothetical condition. After comparison with no perforation and inline arrangement, this hypothetical numerical analysis on perforated aerofoil pin–fin array with staggered arrangement has been advised technically, socio-economic, optimization and material saving point of view.
