Abstract:

Turbulent mixed convection is a complicated flow where the buoyancy and shear forces compete with each other in affecting the flow dynamics. This thesis deals with the near wall dynamics in a turbulent mixed convection flow over an isothermal horizontal heated plate. We distinguish between two types of mixed convection ; low-speed mixed convection (LSM) and high-speed mixed convection (HSM). In LSM the entire boundary layer, including the near-wall region, is dominated by buoyancy; in HSM the near-wall region, is dominated by shear and the outer region by buoyancy.

Abstract:

Mixed convection heat transfer in horizontal and vertical ducts with flow through the duct plays an important role in the design and operation of several industrial equipment involving heat transfer and fluid flow phenomena. The estimation of heat transfer requires consideration of both free and forced convective heat exchange mechanisms, in addition to surface radiation among the internal walls of the duct. Free convection leads to the onset and growth of secondary flows, which interact with the forced convection heat transfer rate, and thereby affecting the overall heat removal rates from a

An accurate measurement of total temperature in turbomachinery flows remains critical for component life models and cycle performance optimization. While many techniques exist to measure these flows, immersed thermocouple based probes remain highly desirable due to well established practices for probe design and implementation in typical industrial flow applications. However, as engine manufacturers continue to push towards higher maximum cycle temperatures and smaller flow passages, the continued use of these probes requires new probe designs considering both improved sensor durability and me

Abstract:

The problem of laminar and turbulent conjugate mixed convection flow and heat transfer in shallow enclosures with a series of block-like heat generating components is studied numerically for a Reynolds number range of zero (pure natural convection) to typically 106, Grashof number range of zero (pure forced convection) to 1015 and various block-to-fluid thermal conductivity ratios, with air as the working medium. The shallow enclosure has modules consisting of heat generating elements, air admission and exhaust slots. Two problems are considered. In the first problem, the enclosure has free bo

碩士<br>國立高雄應用科技大學<br>機械與精密工程研究所<br>97<br>Mixed convection heat transfer in a channel with one periodic oscillating cold block and one heated stationary block is numerically investigated in this study﹒The fluid flows into the channel from the left opening and exits from the opposite end﹒Both the temperature and velocity of the inflow fluid are kept constant﹒In the front of the channel are a oscillating cold block and a heated stationary block﹒The governing equations for micropolar fluid were first presented by A.C. Eringen﹐wherein we furthermore expand the applications to non-Newtonian fluids﹒Th
