Case Study: SolidTrust Technologies achieves 75% pressure drop reduction and 44% maximum velocity decrease with SimScale

SolidTrust significantly reduced noise and improved working conditions for its car muffler design with SimScale

SolidTrust Technologies, an engineering firm serving manufacturing and research sectors, needed to optimize a car muffler to improve air dissipation, exhaust removal, engine performance and reduce exhaust noise. To evaluate multiple design options without costly physical prototypes, SolidTrust used SimScale’s cloud-based CFD/CAE simulation platform to model flow patterns and pressure resistance across proposed muffler designs.

Using SimScale, SolidTrust ran incompressible turbulent CFD simulations at 28 m/s and iterated from an OEM baseline to two redesigned variants—shortened inlet/outlet pipes, added flow diverters and straight fins, then added inter-chamber channels and angled fins. The SimScale-driven process delivered a 75% reduction in pressure drop and a 44% decrease in maximum velocity (with a first iteration already achieving 50% and 38%), about $40k in hardware cost savings, and is expected to significantly reduce noise and improve engine working conditions.
