The aqueous thermal boundary layer
Boundary-Layer Meteorology, 1980This article reviews the available data, measurement techniques, and present understanding of the millimeter thick aqueous thermal boundary layer. A temperature difference between the surface and lower strata, δT, of the order of a few tenths to −1 °C have been observed.

Protuberances in a Turbulent Thermal Boundary Layer
Volume 5: Heat Transfer, Parts A and B, 2011Recent efforts to evaluate the effects of isolated protuberances within velocity and thermal boundary layers have been performed using transient heat transfer approaches. While these approaches provide accurate and highly resolved measurements of surface flux, measuring the state of the thermal boundary-layer during transient tests with high spatial ...

On the convective instability of a thermal boundary layer
Journal of Applied Mechanics and Technical Physics, 1965When the surface temperature of a liquid is a harmonic function of time with a frequencyω, a temperature wave propagates into the liquid. The amplitude of this wave decreases exponentially with distance from the surface. The temperature oscillation is essentially concentrated in a layer of the order of (2χ/ω)1/2, where x is the thermal conductivity of ...

Application of G.P.D.P. to thermal boundary layer
Acta Physica Academiae Scientiarum Hungaricae, 1978The governing principle of dissipative processes is applied to study the steady state thermal boundary layer along a semi-infinite flat plate when plate temperature differs from that of free stream. The thermal boundary — layer thickness is obtained using a third degree profile.

THE INFLUENCE OF THERMAL RADIATION IN TRANSIENT THERMAL BOUNDARY LAYERS
Proceeding of International Heat Transfer Conference 4, 1970Abstract : The investigation examined the effect of an absorbing-emitting gas in a laminar boundary layer near a two-dimensional stagnation point where the wall undergoes a step change in temperature. The flow is considered to be incompressible and steady. The analysis is based on appropriate asymptotic expansions valid for small times.

A thermal boundary layer in a reversing flow
Journal of Fluid Mechanics, 1975Conventional boundary-layer theory cannot be applied when the fluid velocity outside the layer changes direction, and the leading edge of a finite body changes ends. In this paper an approximate method for examining the details of the boundary layer during a single flow reversal (occurring at t = 0) is described. It is based on the expectation that (a)

Thermal boundary layer limitations on the performance of micromachined microphones
The Journal of the Acoustical Society of America, 2018This work examines the extent to which thermal boundary layer effects limit the performance of micromachined microphones. The acoustic impedance of the cavity formed by the microphone enclosure is calculated using both analytical and finite-element methods.

A Study of the Thermal Boundary Layer of the Ocean
1973Abstract : A two-wavelength radiometer and its new computerized data- acquisition/-logging system were installed on the Naval Undersea Center's Oceanographic Research Tower off the coast of San Diego. Data were taken on 14 days during a 6-week period.
