===Transport phenomena===
{{main|Transport phenomena}}

Modeling and analysis of transport phenomena is essential for many industrial applications. Transport phenomena involve [[fluid dynamics]], [[heat transfer]] and [[mass transfer]], which are governed mainly by [[momentum transfer]], [[energy transfer]] and transport of [[chemical species]], respectively. Models often involve separate considerations for [[macroscopic scale|macroscopic]], [[microscopic scale|microscopic]] and [[molecular]] level phenomena. Modeling of transport phenomena, therefore, requires an understanding of applied mathematics.{{sfn|Bird|Stewart|Lightfoot|2002|pp=1–2}}
