A Numerical forced convection heat transfer analysis of nanofluids considering performance criteria
Kirez, Oğuz; Güvenç Yazıcıoğlu, Almıla; Kakaç, Sadık; Department of Mechanical Engineering (2012)
A nanofluid is a new heat transfer fluid produced by mixing a base fluid and solid nano sized particles. This fluid has great potential in heat transfer applications, because of its increased thermal conductivity and even increased Nusselt number due to higher thermal conductivity, Brownian motion of nanoparticles, and other various effects on heat transfer phenomenon. In this work, the first aim is to predict convective heat transfer of nanofluids. A numerical code is created and run to obtain results in a...

Development of a discrete adjoint-based aerodynamic shape optimization tool for natural laminar flows
Kaya, Halil; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2020)
An adjoint-based aerodynamic shape optimization framework for natural laminar flows is developed. A Reynolds-Averaged Navier-Stokes flow solver with the Spalart-Allmaras turbulence model is coupled with the recently developed Bas-Cakmakcioglu transition model in order to predict laminar to turbulent transition onset. In the gradient-based optimization process, the sensitivity derivatives required by the optimization algorithm is obtained by the discrete adjoint method, which is developed for the in-house fl...
Theoretical investigation of conjugate condensation heat transfer inside vertical tubes
Köse, Serhat; Yeşin, Ahmet Orhan; Department of Mechanical Engineering (2010)
Based on the well-known theoretical studies related to the film condensation inside vertical tubes, a known temperature distribution is prescribed as boundary condition at the inner surface of the tube wall. But, in reality, there is a thermal interaction between the condensate fluid and conduction through the wall where the temperature variation along the inner surface of the tube wall is unknown and this unknown temperature profile should be determined by taking account of this interaction. In other words...
