Abstract: A heat transfer mechanism is provided comprising a plurality of turbulators located along a surface of a body, such as a combustion liner. The turbulators have a first side with a first ramp angle, a second side with a second ramp angle, a height, and a base width, where the base width is a function of the height and where the turbulators are spaced an axial distance apart that is a function of the turbulator height.

Abstract: An emissions control system efficiently reduces combustion waste products emitted from a trailer-mounted mobile electrical power generation system. The invention also reduces noise levels associated with power generation. The invention includes several road-transportable duct modules that can be connected together. One module directs the flow of combustion gases from the exhaust of a combustion engine in a power trailer and also provides noise attenuation. Another module mixes the combustion gases with a urea mixture. A third duct module houses a catalyst for removing combustion waste products.
