Type: article
Abstract: Researchers have recently studied ternary-hybrid nanomaterials flow due to their usefulness in nano cryosurgery, atomic power coolants, bio-therapeutic engineering, paper formation, MHD power generator, automobile transformer, fiber production automotive technology, metal processing, renewable energy processes etc. Therefore objective here is to address entropy optimized stagnation point flow of ternary-hybrid nanomaterials by stretching cylinder. Darcy Forchheimer relation for porous space is invoked. Energy expression with novel contribution of Darcy-Forchheimer relation is attended. Three nanoparticles namely copper (Cu), molybdenum disulfide ( Mo S 2 ) and magnesium oxide (MgO) are dispersed with water ( H 2 O ) to form ternary-hybrid nanomaterials. Thermal expression consists of heat generation, dissipation, Joule heating and radiation. Analysis through convective condition of heat transfer is carried out. Entropy optimized flow is under consideration. Newton built in shooting method (ND-Solve) is employed for the solution. Entropy rate, velocity and temperature for involved variables are organized. Numerical outcomes for coefficient of skin friction and Nusselt number are examined. Current study may have relevance in the field of metallurgical engineering and heat polymer moldings. It is found that velocity for magnetic field and Forchheimer variables have decreasing features. Temperature has similar trend through thermal Biot and Brinkman numbers. Higher radiation and Forchheimer number correspond to rise in temperature and entropy rate.
