👉 The term "convolvement" is a concept in fluid dynamics and heat transfer. It refers to the process of convection, which occurs when a fluid flows through an obstacle or boundary. In other words, it describes how fluids move from one part of a system to another without necessarily moving from one fluid into the other. Convolution, on the other hand, is a mathematical operation that involves two variables and their derivatives, often used in physics, engineering, and mathematics. It can be defined
