Theoretical investigation on shocklets in compressible boundary layers
《Applied Mathematics and Mechanics(English Edition)》2014年第8期935-946,共12页袁湘江 刘智勇 沈清 李国良 
Project supported by the National Natural Science Foundation of China(No.10872018)
By the shock relationships, the wavy characteristics and the forming condi-tions of a shock wave are analyzed. The wavy characteristics of an Euler system are stud-ied theoretically. The present research focuses on th...
