In this work, a laser-based thermal pulse technique is presented that simultaneously measures thermal conductivity and thermal diffusivity for liquids, from which the volumetric specific heat can be determined as well. The measurement is based on pho

This paper examines fully developed laminar flow and conjugated forced convection heat transfer in curved rectangular channels. The wall average Nusselt number, Nu , is presented as a function of the wall conduction parameter, φ, the Dean number, De

An investigation was carried out to experimentally determine the thermal conductivities of non-Newtonian fluids in a shear field. Time-independent purely viscous and viscoelastic fluids were considered. A coaxial cylinder apparatus with a rotating ou

The falling needle density meter/viscometer (FNDV) consists of a vertical cylinder which is filled with the test sample. Using a needle launcher at the top of the cylinder, the first needle having a known density is allowed to fall through the liquid

Numerical solutions are presented for fully developed laminar flow for a modified power law fluid (MPL) in a rectangular duct. The solutions are applicable to pseudoplastic fluids over a wide shear rate range from Newtonian behavior at low shear rate

Experiments are reported in which the drag of single liquid droplets settling in a tall column of another lighter immiscible liquid are measured. The experimental data for the eight pairs of liquids that were tested covered a range of droplet Reynold

The following numerical analysis examines the pressure drop and heat transfer characteristics associated with flows of modified power law fluids through concentric annular ducts. The flows considered are steady, fully developed and laminar with const

This paper reports on a numerical study of the drag force on a sphere moving at constant velocity in inelastic non-Newtonian fluids. The intended application of this work is in the use of the falling ball viscometer to determine flow curves for these

A capillary tube viscometer is described that dispenses with direct pressure measurements by comparing capillary tube flow rates of a fluid whose viscous properties are unknown and a standard Newtonian fluid. Since only flow rate measurements are nee

Previous measurements by other investigators of the purely viscous properties of viscoelastic fluids using the falling ball viscometer have been shown to yield anomalous results. These occur because the ball falling through the viscoelastic fluid cre
