You decided to implement CFD simulations into your R&D workflow. Marketing presentations are always fancy and promising, but never tell you whether and how deep the CFD can help you with the real work. Can help you to analyze your product design and give you an critical opinion on the CFD benefits for your situation.
I spent many years by providing services on thermographic inspection of buildings. It looks easy to take the picture by a thermocamera but than what. There are always blue and red areas on the picture but the know-how is in correct interpretation what temperature is critical and what is still normal
Computational fluid dynamics simulations offer a chance to visualise and measure and predict the fluid flow together with conjugated heat transfer or combustion regimes. Can help with optimizing your heat exchanger, burner nozzles or stabilizing the flow in the ducting? Here we are.
Through all my work I focus on the deep understanding of current issue, understanding all the boundary conditions around and mainly on RESULT INTERPRETATION. It is a piece of cake to perform a simulation and get good results when all the boundary conditions are exactly known and all around is ideal.
This is the academical work, real world is radically different.
"I was working with Marek in the same team focused on numerical simulations at the beginning of my professional career. As an experienced engineer, Marek taught me a lot of practical skills in numerical modelling and how to provide the best simulation approach for real engineering problems. His ability to clearly explain the essence of the simulation tasks from theoretical and practical point of view helped me to grow in my profession much faster.
I have enjoyed more than 2 years working together with Marek thanks to his positive working attitude and professional support."
"Over the past 12 years, Marek has been the sole computational fluid dynamics (CFD) resource for the global Honeywell industrial combustion R&D team. During that time, Marek was our "go-to" CFD expert on first-of-a-kind industrial burner concepts and inventions. Marek was also requested by our application engineering teams, to help solve field related combustion, noise, process instability or emissions issues. These issues had usually proven to be beyond the abilities of our field people to solve with typical on-site adjustments or modifications. Providing critical CFD simulation results to help understand and resolve the issues, Marek worked directly with customer engineers, service technicians and local sales leaders to resolve these issues, usually under considerable time pressure.
On all assignments, Marek provided exceptional modeling skill, curiosity, solution generation and a good, positive attitude. He helped drive the development of multiple new burner designs. For these contributions, he was included on multiple US and international patents granted to the combustion team.
"Marek was able to make our vision reality in less than 12 months, helped me a lot in increasing capability of Design Engineering Department, while communicationg very frequently with, meeting and exceeding customer expectations. Marek is self learner able to identify and close the gaps in CFD field within but also with support outside of immediate team and company, therefore I would recommand Marek also to a leader positions."
A nozzle in a burner assembly is configured to produce a flame. The nozzle is configured to include a fuel-discharge outlet and to conduct fuel along a pathe in the nozzle to the fuel-discharge outlet. Pressurized primary oxygen is provided to mix with fuel discharged by the nozzle to produce a mixture that can be ignited to produce a flame. Staged oxygen is provided to the flame in a region downstream from the nozzle.
Devices, methods, and systems for utilizing a burner with a combustion air driven jet pump are described herein. One burner pparatus includes a jet pump located inside a burner housing, the jet pump having a combustion air inlet that receives combustion air, a chamber to receive the combustion air from the combustion air inlet, and a tapered portion of the chamber that tapers to an outlet having a smaller diameter than the diameter of the inlet.
The pre-mix burner assembly includes a jet pump comprising a combustion air tube, a flue gas inlet, and a suction chamber. The combustion air tube has an inlet and a tapered nozzle, and it is coneected to the suction chamber and the furnace chamber or the other flue gas source. This suction chamber surrounds the combustion air tube, and it has a jet pump nozzle with a discharge. The combustion air exiting the combustion air nozzle creates a negative pressure in the suction chamber and draws flue gas into the suction chamber. There is a burner housing positioned downstream of the jet pump discharge. There is a fuel gas inlet connected to a mixing tube in the burner housing, and a burner block connected to the outlet of the burner housing.
one of the topic which is not known in wide public is the question of the scientific definition of something what is very virtual – thermal comfort. And yet, we have it! This was actually Read more…
