HE­LI­COPTER THINK­ING

Sky at Night Magazine - - BULLETIN -

An al­go­rithm used by he­li­copter de­sign­ers to pre­dict the flow of air around ro­tor blades has been adapted to help astronomers en­vi­sion the tur­bu­lent move­ment of ma­te­rial around plan­ets and gal­ax­ies.

“Space is full of gas, dust, flu­ids and tur­bu­lence,” says Dar­ryl Seigman from Yale Univer­sity, who led the study. “We wanted to do a bet­ter job of ac­count­ing for the swirling of all this ma­te­rial. We were stunned by the level of de­tail we were able to achieve.”
