Design Concepts for a New Guarded Hot Plate Apparatus for Use Over an Extended Temperature Range

October 1, 2002

Author(s)

D R. Flynn, Robert R. Zarr, Mahn-Hee Hahn, William M. Healy

The National Institute of Standards and Technology is building a new guarded hot plate apparatus (GHP) for use at temperatures from 90 K to 900 K, with provision to conduct tests in various gases at controlled pressures from 0.013 Pa to 0.105 MPa

Thermal Modeling of Multiple-Line-Heat-Source Guarded Hot Plate Apparatus

October 1, 2002

Author(s)

William M. Healy, D R. Flynn

The National Institute of Standards and Technology is building an advanced-design guarded hot plate apparatus of advanced design to provide very accurate thermal transmission properties for specimens of thermal insulation 500 mm in diameter, with

On the Validity of the Adiabatic Spreading Assumption in Droplet Impact Cooling

October 1, 2001

Author(s)

William M. Healy, J G. Hartley, S I. Abdel-Khalik

The effect of heat transfer on the spreading of a water droplet impacting a heated surface has been numerically investigated. The aim is to assess the validity of commonly made assumptions in spray cooling models which ignore heat transfer during the

Using Finite Element Analysis to Design a New Guarded Hot Plate Apparatusfor Measuring the Thermal Conductivity of Insulating Materials

October 1, 2001

Author(s)

William M. Healy

The National Institute of Standards and Technology (NIST) is developing aguarded hot plate apparatus to measure the thermal conductivity of thermal insulation over a temperature range from 90 K to 900 K. The apparatus will create one-dimensional heat flow

Surface Wetting Effects on the Spreading of Liquid Droplets Impacting a Solid Surface at Low Weber Numbers

December 1, 2000

Author(s)

William M. Healy, J G. Hartley, S I. Abdel-Khalik

A modification to the Kurabayashi-Yang equation for predicting the maximum spreading ratio of a liquid droplet impacting a solid surface has been made to account for effects of the contact angle between the spreading liquid and the impact surface. A
