Internal flow subjected to an axial variation of the external heat transfer coefficient
… subjected to an axial variation of the external convection coefficient is presented. Since the variable boundary condition parameter causes the problem to become nonseparable, conventional techniques do not apply. Instead, the Green's function technique is used to convert the governing partial …

The effect of roughness element thermal conductivity on turbulent convection.
… with surface depositions. Depending on the local convection coefficients, low thermal conductivity deposits may create situations where temperature changes along the heights of the elements are important and must be considered in predicting the overall surface convection coefficient. Using four …

On the thermomechanics of localizing pseudoelastic transformations in NiTi materials and structures
… heat exchange with the airstream is modeled by a convection boundary condition on the outer surface. The convection coefficient is chosen so that the calculated rate of transformation matches the measured one. The analyses reproduce the transformation temperatures, strains, and inhomogeneous …

A Model of Transient Heat Transfer in a Packed Bed of Alumina Particles
… more reliable method to calculate heat transfer coefficient between fluid and solid, and investigating the effect of neglecting temperature dependency of materials properties. As the storage heat system has a vertical storage vessel, the dominant heat transfer mechanism from the boundaries of the …

Approximate Thermal Modeling of Radiofrequency Cardiac Ablation
… the engineering model. The effect of the convection coefficient (h), the depth at which the point source is located (zo), and the power dissipation rate (P) on the 50 ˚C isotherm in the cardiac tissue is shown. The accuracy of the approximate model depends greatly on the values of these …

Heat Transfer Assessment of Aluminum Alloy Corrugated Naval Ship Deck Panels under VTOL Aircraft Thermal Loads
The behavior of aluminum alloy ship deck panels under the thermal loads of Vertical Take-off-and Landing (VTOL) capable aircraft has become a question of interest with the introduction of new primarily aluminum alloy ships to the U.S. Naval Fleet. This study seeks to provide an initial …
