Internal solitary waves (ISWs) are solitary waves that occur within stably stratified water columns where density changes are due to changes in temperature, salinity, or both. The pycnocline, where density changes rapidly with depth, acts as a waveguide for internal wave motion. ISWs are characterized by different modes. Mode-1 ISWs are the most frequently observed mode and displace isopycnals in only one direction (depression or elevation). Mode-2 ISWs displace isopycnals in two directions and are characterized by concurrent elevation and depression of isopycnals in the upper and lower layers, respectively. Mode-2 ISWs are commonly observed as convex bulges that propagate along the pycnocline. Recently reported studies on the strongly nonlinear theory of large-amplitude ISWs have reported a unique class of mode-2 ISWs characterized by multi-humped profiles. So far, limited investigations have been conducted on these unique mode-2 waves, and no study has reported laboratory-based generation of these exotic waves. Thus, numerical and experimental studies should be performed to investigate the physical generation of such waves. Simulations should be performed to discern the critical parameters required to generate these unique waves. Simulations will be performed using open-source software, the Spectral Parallel Incompressible Navier-Stokes Solver (SPINS).
Open source solver, SPINS (Spectral Parallel Incompressible Navier-Stokes Solver). SPINS consists of a bunch of C++ source files and a bunch of case files, and it requires four libraries. UMFPack, AMD, and Blitz++ are supplied with SPINS, and it uses the system-installed FFTW. As a parallel program, it also requires MPI, so you must ensure that your environment refers to a system-installed MPI suite
