A computer model explains how to make perfectly smooth crepes

Perfect crepe-making is all in the wrist, according to physics.

Using a computer simulation, two fluid dynamics researchers have devised a step-by-step guide for preparing perfectly flat crepes. Their strategy, described in the June Physical Review Fluids, involves tilting and rotating the frying pan in circles. Besides making picture-perfect pancakes, this technique might be useful for chocolate manufacturing, as well as tasks outside the kitchen, such as applying coatings to smartphone displays, solar cells or circuit boards.

“The motivation for this study literally comes from the kitchen,” says Edouard Boujo of École Polytechnique in Palaiseau, France.

One day, his colleague Mathieu Sellier was frustrated that all of his crepes turned out uneven. Selliers wife reminded him that, as a fluid dynamicist, he of all people should be able to solve this problem. Sellier, of the University of Canterbury in New Zealand, accepted the challenge and teamed up with Boujo to create a computer simulation of a crepe cooking in a pan.

The simulation accounted for the pans orientation and temperature, as well as the batters changing thickness as it cooks. Sellier and Boujo analyzed this simulation using a mathematical technique called adjoint optimization to discover the pan motion that maximizeRead More – Source
