Abstract: In this article, we study the exhaustive analysis of nonlinear wave interactions for a 2× 2 homogeneous system of quasilinear hyperbolic partial differential equations (PDEs) governing the macroscopic production. We use the hodograph transformation and differential constraints technique to obtain the exact solution of governing equations. Furthermore, we study the interaction between simple waves in detail through exact solution of general initial value problem. Finally, we discuss the all possible interaction of elementary waves using the solution of Riemann problem.

Key words: Elementary waves, wave interactions, Riemann problem, simple wave, differential constraints, Hodograph transformation
