Laminar natural convection within long vertical uniformly heated parallel-plate channels and circular tubes

Creator:: Vorayos, Nat
Abstract:: The problem of simple mathematical models of laminar natural convective flow within a long vertical parallel-plate channels and circular tubes kept at uniformly heated walls is revisited to seek a clear physical understanding of heat transfer mechanisms. A series solution method to analyze the fully developed flow and an integral...

Fluid forces on and flow configurations around a circular cylinder near a plane boundary

Creator:: Tavolacci, Don
Abstract:: The flow configurations around and the forces acting on a circular cylinder with its axis parallel to a nearby plane boundary and subjected to a uniform flow were investigated. The flow conditions, which were perpendicular to the cylinder axis and parallel to the plane boundary were investigated experimentally and theoretically....

Effects of orifice geometry and surface boundary condition on heat transfer of impinging jet array

Creator:: Kanokjaruvijit, Koonlaya.
Abstract:: The effects of the orifice geometry and the surface boundary condition on the heat transfer distribution to a flat surface of an impinging jet array were investigated. The jet array impinged normally onto the surface which was either isothermal or had a uniform heat flux. The experiments were performed for...

Numerical design of a high-flux microchannel solar receiver

Creator:: Rymal, Charles
Abstract:: This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...

Flow characteristics of semi-confined impinging jet arrays

Creator:: Dano, Bertrand P. E.
Abstract:: The present study proposes to investigate the flow structure of different arrays of jets impinging on a flat surface enclosed by three walls, creating a channel that forces the air to leave in one preferential direction, generating a self sustain crossflow. Details of both the mean and some turbulence quantities...

Experimental investigation of supercritical heat transfer of carbon dioxide in parallel square microchannels with a single-wall constant heat flux boundary condition

Creator:: Zada, Kyle R.
Abstract:: In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat...

Investigation into the role of strength and toughness in composite materials with an angled incident crack

Creator:: Grimm, Brian A.
Abstract:: Understanding the mechanical behavior of composite materials requires extensive knowledge of fracture behavior as a crack approaches an interface between the bulk material and the reinforcement structure. Overall material toughness can be greatly influenced by the propensity of an impinging crack to propagate directly through the substrate or deflect along...

Turbulent Heat Transfer of Supercritical Carbon Dioxide in the Proximity of the Pseudo-Critical Point with Non-Uniform Heat Flux Boundary Conditions

Creator:: Jajja, Saad A.
Abstract:: Seven decades of supercritical heat transfer research have not seen an attempt to characterize turbulent thermal transport in internal flows subject to asymmetric heating. Existing heat transfer models therefore do not account for phenomena that dictates thermal transport, in the proximity of the pseudo-critical point, for non-uniform heating. Additionally, past...
