DINAK is a company specializing in the production of chimneys and ventilation systems. To be competitive in the global market, the company needs to optimize its chimney designs in order to reduce CO2 emissions and improve energy efficiency. This improvement has been made possible through software and simulations using HPC technology.

Duration in months: 18
Problem Description
The reduction of emissions requires the design of optimised chimneys. Simulation plays an important role in the design of new chimneys. In a building with stoves it is necessary to install a ventilation system to assure an effective and regulation-compliant exhaust system and a proper air renovation ratio. The problem is complex because there are many variables and the simulation must be sufficiently accurate and detailed.
Goals
Virtual prototyping
Challenges
This experiment aims to implement high performance computing (HPC) for fast time-to-solution and a user-friendly interface for easy access to simulations of chimneys.
Innovation results
This experiment has demonstrated that the design of concentric chimneys using HPC-based simulation resources is feasible and accurate. The results from this solution have been successfully validated against commercial software and experimental data.
Business impact
The experiment gives DINAK a saving of over €12,250 per design which is €49,000 per year. The optimised design through the use of HPC, enables DINAK products to pass CE Mark tests with a zero failure rate with a consequent cost reduction.
