Uncertainty and Local Sensitivity Analysis of View Factors for Steady-State Conjugate Heat Transfer Problems

Including Solar Radiation in Sensitivity and Uncertainty Analysis for Conjugate Heat Transfer Problems

“…Since thermal stresses and deformations were investigated, deformed view factors were approximated by a first order Taylor series expansion, which showed some descent results. In another paper (Bhatia & Livne, 2009) they also showed a way to put all temperature dependent parameters into the main diagonal of a matrix with consequent This article is a continuation of previously published papers (Rauch & Almbauer, 2010a;Rauch, 2011b) that dealt with steady-state uncertainty estimations of some parameters for conjugate heat transfer with cavity radiation. Later, the transient (Rauch, 2011a) case was investigated.…”

“…12 dimensionless UF for q solar , fluid temperature T f , and conductance C are shown. The corresponding equations were published in Rauch & Almbauer (2010a) and Rauch (2011b). In none of the nodes investigated, exceeded the UF the value 1.…”

“…Later, the transient (Rauch, 2011a) case was investigated. The present author also treated view factors in conjugate heat transfer analysis for steady-state (Rauch & Almbauer, 2010) and transient (Rauch, 2011) cases.…”

“…Either way, the number of possible parameter settings usually rises with the number of models employed. To serve as an example, Rauch et al (2008a) were involved with an underbody simulation of a car. The exhaust system transported the exhaust gas out of the engine and heat was released along the piping system.…”

On Uncertainty and Local Sensitivity Analysis for Transient Conjugate Heat Transfer Problems

“…It can be regarded as a continuation of Taylor's work [3,4] by expanding his approach by conduction and convection. In a related treatment, Rauch and Almbauer [11] focused on sensitivities of view factors in CHT problems.…”
