Grand Unified Theory from the Perspectives of Heat Transfer and Fluid Mechanics
Abstract: It was shown by Alaettin Yildiz [A. Yildiz, Dissertation D83, Technical University of Berlin, Germany (1965)] experimentally in mid 1960s that there exists previously unknown critical value for the rotation rate of a cylinder above which occurs a sharp transition in the quantitative dependence of heat transfer on the system parameters. He considered a rotating cylinder that was subjected to an airstream along the axis of rotation. His objective was to characterize the measured aerodynamic heat transfer in terms of the dimensionless numbers describing the system. The convective heat transfer was closely related to the characteristics of the flow around the vicinity of the cylinder surface. In this project we explore the possibility of similar phenomena in the early stages of Big Bang.

A. Yildiz showed experimentally in 1965 that there exists previously unknown critical value for the rotation rate of a cylinder above which occurs a sharp transition in the quantitative dependence of heat transfer on the system parameters [1]. His objective was to characterize the measured aerodynamic heat transfer in terms of the dimensionless numbers describing the system. The convective heat transfer was closely related to the characteristics of the flow around the vicinity of the cylinder surface. (See Figure 1)
Figure 1 Heat transfer from a rotating cylinder without forced flow. The experimental result presented Nusselt number as a function of the dimensionless expression dw^2/g (i.e., Yildiz number) where w and g are angular and gravitational acceleration, respectively. The abrupt change in the slope is because of the significance of dw^2/g on turbulent heat convection.
In this project we investigate the related phenomena that might had occurred in early stages of Big Bang.
