“…The zonal method (Lou and Huang, 2000), the network model (Zueco and Campo, 2006) and the finite element method (Daun et al , 2003a, b, 2002, 2006) are the commonly used numerical methods which provide a discrete algebraic model for the problem. Simulation of the heat exchange between the radiation panels and a moving circular cylinder in a two‐dimensional oven using the finite element method has been discussed by Mehdipour et al (2010).…”

“…Xiao et al (2006a) proposed that instead of using the TTT curve as the design target, one may employ a paint cure window and try to confine the heat transfer process at every point of the painted body inside the cure window. To employ the cure window, the TTT curve needs to be converted to another curve in which the horizontal axis represents the curing time (CT in Figure 1(b)) and each point along the vertical axis shows the minimum applied temperature corresponding to the relevant CT. Further details can be found in work of Mehdipour et al (2010).…”

“…Therefore, the objective function can now be defined as follows: Equation 3 EIT * is also called the target nominal cure point (NCP). An alternative definition for the OF 2 has been defined and used in work of Mehdipour et al (2010): Equation 4 Equation 5 Minimum and maximum time durations (Φ min and Φ max ) corresponding to the reference temperature ( T r ) in equation (2) are shown in Figure 1(d) as points 1 and 2. The NCP in Figure 1(d) is simply a preferred, factory‐recommended, curing point between points 1 and 2 along the T r line.…”

“…The focus in this paper is on the proper definition of the objective function in a radiation oven optimum design problem. While the heat transfer simulation and optimisation techniques are the same as the work of Mehdipour et al (2010), a novel objective function is defined and used here. It is shown that by defining the objective function based on the equivalent isothermal temperature (EITe) instead of the EIT, the design procedure becomes more robust and an optimum solution is obtained in fewer design iterations.…”

“…The new objective function is discussed afterwards and it is used then to solve an example problem. For the sake of brevity and clarity, the unnecessary details are not discussed here and the reader is referred to the previously published accompanying paper (Mehdipour et al , 2010).…”

PurposeThe purpose of this paper is to model radiation ovens and to propose a method capable of designing this kind of oven for the paint curing application. Providing a uniform cure condition on the body, especially bodies of complicated geometries, needs accurately‐designed ovens. An algorithm with high speed and high convergence capability is the most serious requirement for designing ovens of this kind.Design/methodology/approachIn this paper, the state of the art in dynamic optimisation of radiation paint cure ovens is reviewed and a novel objective function, based on paint cure window, is proposed to be applied for designing radiation ovens. It has been shown that the proper definition of the objective function in such problems makes the mathematical model more robust and hence facilitates the convergence of the design iterations.FindingsThe computational results provide some information regarding the design space topology and show that the proposed objective function speeds up the convergence of the design procedure by an order of magnitude as compared to the currently used industrial‐standard objective function.Practical implicationsDetermination of curing condition is an important requirement for designing a new oven or changing the working condition of an existing oven. In this research, a practical method is proposed for improving design procedure of cure ovens to make the method both time and cost efficient. The method is specifically implemented on paint cure ovens.Originality/valueThe quality of cured paint is usually a prominent issue that directly takes influence from the curing condition of ovens. For the complex geometries of curing body in commonly designed ovens, some areas are not properly cured or may be burnt. This issue is a significant defect in coating industry. Designing ovens with the proposed method in this paper guaranties the provided curing condition by the oven and therefore the curing quality.

The paint shop plant, as the largest energy consumer in the automotive manufacturing process, requires special attention to optimize energy efficiency and thermal management, reduce environmental impact and diminish the total costs to improve marketability. The current review covers the description of the automotive paint shop, recognition of the paint film layers, characterization of the paint spray applicators and evolution of their technology's advancement, explanation of the coating processes development, and investigation of the curing ovens thermal procedure in an automotive production stage. After systematically recalling pioneering studies dealing with the coating techniques and the ovening strategies, this paper focuses on reviewing recent findings conducted with improved modern methods in this subject area for higher sustainability and efficiency. Critical performance factors in developing surface durability, corrosion protectivity, paint material consumption, and environmental pollution are discussed. Focus is brought to the electrostatic spray-painting procedure flow physics understanding, particularly the complicated three-dimensional behaviors of paint droplets formation, distribution, control and deposition on the body in constructed spray plums. Then, the baking and drying process of the produced film layer in the curing oven is precisely reviewed. The review additionally aids in the identification of knowledge gaps in the literature that should be addressed in future research.
