Experimental study on the heat transfer of gas with coagulative particles flowing through a packed granular bed filter

New Formula for Direct Prediction of the Effective Thermal Conductivity of the Ellipsoidal Granular Bed at High Temperatures

“…Packed beds are frequently encountered in the mineral, chemical, , and environmental industries, and the thermal properties, especially the effective thermal conductivity (ETC), of packed beds are of great significance for their optimal design and operation. , Considering the mineral industry as an example, 160 million tons of steel slag (corresponding to the output of 1.065 billion tons of crude steel, 56.7% of global output) were generated in China’s iron and steel industry in 2020, which had a heat equivalent of 41,000 tons of standard coal . The temperature of the discharged steel slag is over 1000 °C, and the waste heat is of a high quality.…”

Analysis of natural convection and the generation of entropy within an enclosure filled with nanofluid-packed structured pebble beds subjected to an external magnetic field and thermal radiation

“…This method has many benefits, including high thermal efficiency, quick response times, affordability, and the ability to scale up easily [1]. Packed beds find extensive application across various industries, including chemical reactors, distillation processes, waste heat recovery, hydrogen production, and dust removal devices [2][3][4]. Random packed beds are often favored for their ease of construction and operation, but there has been growing interest in structured packed beds due to their unique abilities and potential uses in recent years.…”
