Comparative energy and exergy performance investigation of forced convection solar air collectors with cherry stone powder
Abuşka, Mesut; Şevik, Seyfi; Kayapunar, Arif (Pergamon-Elsevier Science Ltd, 2019)The purpose of this study is to design new solar air collectors (SACs), to ensure that designed SACs continue to operate in cloudy weather and after sunset and to evaluate in terms of energy and exergy whether the cherry ... -
A comparative experimental performance evaluation of solar air collector having absorber plate with convex oval-trench dimple
Abuşka, Mesut; Şefik, Seyfi; Özdilli, Özgür (Springer Science and Business Media Deutschland GmbH, 2023)The purpose of this research is to examine how convex oval-trench dimples placed staggered on a solar air collector's absorber improved vortex heat transfer. At air mass flow rates of 0.013, 0.027, and 0.036 kg/s, convex ... -
A comparative investigation of the effect of honeycomb core on the latent heat storage with PCM in solar air heater
Abuşka, Mesut; Şevik, Seyfi; Kayapunar, Arif (Elsevier Ltd, 2019)The aims of this study were to comparatively investigate the effect of using PCM and honeycomb as the internal fin structure in the PCM panel on the thermal performance of solar air heater. The tests performed at six air ... -
The effect of blowing direction on heat sink performance by thermal imaging
Abuşka, Mesut; Şevik, Seyfi; Altıntaş, Volkan (Yildiz Technical University, 2018)Heat sinks (HSs) are designed for the mechanical, electrical and electronic components that generate heat in considerable amount. For this purpose, an aluminum conical pin fin heat sink is designed. Aluminum conical pin-fins ... -

Abuşka, Mesut; Şevik, Seyfi (Elsevier Ltd, 2017)An experimental investigation has been carried out to study the effect of energy, economic, and environment of SACs which are smooth and roughened by v-groove protrusions arranged made of copper and aluminium materials. ... -
Enhancing the thermal performance of a solar air heater by using single-pass semi-flexible foil ducts
Şevik, Seyfi; Abuşka, Mesut (Pergamon-Elsevier Science Ltd, 2020)This study focused on improving the thermal performance of a solar air heater (SAH) using a single-pass semi-flexible foil duct that can be applied directly as an absorber without requiring any surface modification. In ... -
Experimental analysis of solar air collector with PCM-honeycomb combination under the natural convection
Abuşka, Mesut; Şevik, Seyfi; Kayapunar, Arif (Elsevier B.V., 2019)Phase change material (PCM) is at the head of materials commonly used in latent heat storage. However, usually the main problem is that the heat conductivity of PCMs is low. Therefore, a novel solar air collector (SAC) ... -
Experimental and numerical investigation on the thermal performance of linear LED housings under forced convection
