    Abstract: In this thesis, the numerical solution of navier stockes equations and turbulent equations have also been investigated in fluent software, to investigate baffle type change from cut off to helical in shell and tube heat exchanger. RNG K-ε turbulence model was used to perturbations modelling. The main objective of baffle changing in thesis is increa... Show More

    Abstract: This paper presents dynamic analysis studies of planar parallel flexible 3-RRR manipulator with and without considering the flexibility of mobile platform. Initially, by treating all the members of the manipulator as flexible, the joint displacements, reaction forces and stresses are obtained during a specified trajectory tracking in Cartesian spac...

    Abstract: Hard magnetic material Nd2Fe14B was synthesized via powder metallurgy technique. The magnetic powder Nd2Fe14B was produced by mixing Neodymium powder (Nd), Iron powder (Fe), and Boron powder (B) in a vacuum and then followed by firing process at 720ºC. The Nd2Fe14B powder produced was grained with addition of 0.3g and 0.7g Neodymium respectively. T... Show More
