The idea of this special issue of mathematical problems in engineering is to consider the study and applications of modeling and simulation technology in drying technology. Drying science is very old in human history and is not only related to the food processing industry, but also extends to a broad range of applications in the chemical, biochemical, pharmaceutical, and agricultural sectors. The drying of various materials at different conditions in a wide variety of industrial and technological applications is a necessary step either to obtain products that serve our daily needs or to facilitate and enhance some of the chemical reactions conducted in many engineering processes or make them environmentally safe. Drying processes consume large amounts of energy, and any improvement in existing dryer design and reduction in cost will be immensely beneficial for the industry. Drying is inherently a cross- and multidisciplinary area because it requires optimal fusion of transport phenomena and materials science because the objective of drying is not only to supply heat and remove moisture from the material but to produce a dehydrated product of specific quality.

In order to improve the drying efficiency, lower the drying cost, and get the high-quality product, the modeling and simulation technology has been one of the most important research areas in drying technology.

Therefore, since modeling and simulation plays a very important role in drying technology developments, this call for papers is posted, seeking for papers related to the study of the engineering applications devoted to the drying modeling and simulation. Potential topics include, but are not limited to:

• Drying theory and its application
• Drying process modeling and simulation
• Dryer modeling
• Drying model validation
• Heat and mass transfer modeling of drying process
• Control and optimization of drying process
• Dewatering and dehydration process modeling
