Flow

We develop all our models using the SolidWorks Professional and FlowSimulation system. During the combustion chamber development, we conduct a series of simulations to optimize the design for the best performance, safety, and durability. We verify safety clearance distances and simulate real combustion conditions to determine the temperature of all materials used. Through animations, we evaluate the velocity, density, quantity, temperature, and pressure of the combustion gases. Based on the findings, we modify the airflow path and regulation to achieve optimal flushing for self-cleaning glass.

Load analysis to verify maximum temperatures in the combustion chamber.

Flow simulation for the secondary glass flush in the fireplace insert, as seen in images A to D. Image A illustrates the combustion chamber at startup, where optimal temperatures and airflow for flushing have not yet been reached. Conversely, as the temperature increases (images B to D), the airflow accelerates, reaching the bottom edge of the door. This process effectively cleans the glass, preventing any impurities from accumulating on the door glass. The bottom row of images depicts the distribution of air across the entire width of the door glass. Through this simulation, we verify the airflow to ensure that there are no areas without glass flushing. As a result, the door glass remains clean across its entire width. This is one of many differences between our products and those found in hobby markets.

Progressive ignition of fuel in the combustion chamber, simulation of temperatures, fireplace inserts, from figure A, the coldest, to figure D, the warmest, with the combustion chamber fully heated (100% ignited fuel). In this simulation, we verify the function of air regulation, air distribution for combustion, and also the maximum temperatures reached by stressed materials. For example, in figure D, it is evident how the incoming cool air from the regulation cools the gases in the chamber and thereby the glass of the door.
