Effect of cooking and drying on the thermal conductivity of rice

Testing of thermal properties of foods is essential for operation and control of food processing plants. In this paper, the thermal conductivity of rice and the drying of cooked rice is measured. These measurements are determined using a transient line source over a temperature range ...

Temperature influence on the effective thermal conductivity of cellular metals measured in stagnant air

This study aimed to experimentally measure the thermophysical properties of cellular metals, focusing on effective thermal conductivity. The transient plane source (TPS) technique was used to measure the thermal conductivity of hollow sphere structures from different steel alloys and open cell structures made of iron-chromium-aluminum ...

Influence of Sliding Speed on the Tribological Characteristics of Si3N4-hBN Ceramic Materials

A disc of a composite ceramic material composed of silicon nitride (Si3N4) and 20% hBN was prepared and its tribological characteristics were investigated by sliding a Si3N4 pin across its surface at different sliding speeds. The friction coefficient and wear coefficient were determined for ...

Influence of the volume fraction and the nature of fine lightweight aggregates on the thermal and mechanical properties of structural concrete

The thermal and mechanical properties of concrete in which normal weight aggregate has been substituted with lightweight aggregates were investigated. The properties were found to be dependent on the volume fraction of the lightweight aggregate, as well as on the nature and quality of the ...
