Mixed convection in laminar/turbulent separated backward-facing step flows
<p>"Mixed convective heat transfer results for two-dimensional laminar/turbulent flow in a duct with a backward-facing step are reported. The two walls forming the duct are maintained at uniform but different temperatures. The straight wall is maintained at the inlet air temperature, while the …

Magnetohydrodynamic Effects On Mixed Convection Flows In Channels And Ducts
This work focuses on magnetohydrodynamic (MHD) mixed convection flow of electrically conducting fluids enclosed in simple 1D and 2D geometries in steady periodic regime. In particular, in Chapter one a short overview is given about the history of MHD, with reference to papers available in …

Mixed convection and heat management in the Mars gravity biosatellite
… the tendency for heated air to move by free convection toward the axis of rotation. Dominance of forced convection throughout the payload module will ensure nearly isothermal air and effective heat rejection from the payload to the bus module via fan/heatsink/thermoelectric cooler units. …

An experimental investigation of mixed convection heat transfer in a rectangular enclosure
Mixed convection heat transfer was studied in a well instrumented, office size, rectangular enclosure. Surface and air temperatures were measured, convective heat fluxes were calculated, significant parameters were identified, and Nusselt number correlations were developed for various flow field …

The flow structure under mixed convection in a uniformly heated vertical pipe
… The high heat flux places the flow into a mixed convection regime, which is not yet fully understood. One of the issues of mixed convection is that the transition from laminar to turbulent flow is not clearly defined in the existing literature. Review of previous work on heat transfer …

Simulation of steady mixed convection in a lid-driven cavity filled with newtonian fluid by finite volume method
The steady mixed convection flow in a lid-driven cavity was simulated. The cavity was filled with a Newtonian fluid, both vertical walls are adiabatic, while the horizontal walls were either fixed cold and uniformly/oscillatory heated. Firstly, the effect of internal heat generation or absorption …

Heat and Mass Transfer in Reactor Core During a Loca-Single Channel Analysis (Mixed Convection, Numerical, Flow, Thermal-Hydraulics)
Ability to predict the scenario following a loss-of-coolant accident (LOCA) is of central importance in the safety analysis of water reactors. During LOCA, the reactor core is uncovered and the residual water inventory is boiled off by fission products decay heating. For the Three Mile Island …

A New Numerical Method--Asymptotically Simplified Iteration Method With Patching as Applied to Free and Mixed Convection Heat Transfer
… natural structure of high Rayleigh number free convection, which consists of thin thermal and viscous boundary layers surrounded by a region of negligible viscous and conductive influences. Iteration techniques appropriate for each region are obtained from considerations of the asymptotic …

Unsteady hydromagnetic chemically reacting mixed convection MHD flow over a permeable stretching sheet embedded in a porous medium with thermal radiation and heat source/sink
The unsteady hydromagnetic chemically reacting mixed convection MHD ow over a permeable stretching sheet embedded in a porous medium with thermal radiation and heat source/sink is investigated numerically. The original partial di erential equations are converted into ordinary di erential equations …

Using control surfaces to evaluate weighting coefficients for fast thermo-fluid reduced-order-modelling strategies
… thermo-fluid modelling in a forced, natural or mixed convection regime. The thesis replicates an existing methodology in the modelling of forced convection, and adapts it to the natural and mixed convection regime. This resulting methodology uses a variant of the standard computation known as …
