Transient forced convection heat transfer due to exponentially increasing heat input to a heater is important as a database for the safety assessment of the transient heat transfer process in a very high temperature gas-cooled reactor (VHTR). Forced convection transient heat transfer for helium gas flowing over a cylinder in a narrow channel was experimentally studied at various periods of exponential increases in heat input. The test heater was mounted *

“…Colver [22] studied three heaters in conical shapes and predicted their performances in order to reduce the temperature of the coils and reach a uniform temperature of the air. M.Shibahara, Q.Liu, and K.Fukuda [23] experimentally and numerically investigated transient forced convection heat transfer of plate heater for nitrogen gas due to exponentially increasing heat input. M.C.Wang et al [24] studied flow and heat transfer property simulation performed on both helical and segmental baffle electric heaters of equilateral tube layout with one-plus-two U-tube units.…”

The novel segment electric in-line process electric heaters heater designed to heat various fluids analyzed in this work. The complete electric heater consists of several hollow cylindrical segment heating elements. The segment heating elements can vary positioned in relation to the fluid flow. The total power of the segment process heater is equal to the sum of the power of all heating segments and is 0.756kW. Volumetric air flow variations in the amount of 0.001m3s-1, 0.002m3s-1 and 0.003m3s-1. The heating elements are positioned in the three combinations in relation to the direction of the fluid flow. The comparative numeric analysis, conducted for this work, has the goal to determine the influence of the arrangement of segment heaters on the overall energy efficiency of the segment electric heater. In order to verify the results of the numeric simulations carried out and experimental investigations of the segment electric heater.
